This is exactly was i put those tyres are pants at silverstone
i was only 3.2 off nevermans time in a stage 1 evo 6rs 375bhp,,
Only mods remap, filter , exhaust, bc crappy coilovers, no other mods
Would of hoped for around the 1 min dead
Tyres is a massive deal on those sprints
#I ran the rd legal dunlop super soft dz02's
Chin up shaune,,
I had a bad feeling you would get mullered
The mlrss is a very good class of competitors for sure who take it far to serious

So, might be worth fitting a temperature sensor in the plenum, or TMIC exit pipe? Or, if you have an '05 JDM STi, rewiring to make use of the inlet temperature sensor that's already conveniently fitted there, but not used It goes to ECU pin E14, whereas the MAF sensor goes to B27

Shaun

John,
To be fair, I can't blame anything but my atrocious driving yesterday. Yes granted, the RE070's didn't provide the best grip / confidence (as you found out lol), but my fastest lap was a 1:09 in the morning. I was way off what I should been capable of running and I feel I should of been in the 1:05's. It was as if I had never driven on track before..... I was all over the place.

It maybe worth me getting Rich to use the charge air temp sensor on the block if possible then.

Lee,
Thanks for your comments of support, but as I have said I can't excuse my horrendous driving yesterday. New car or new track..... it's not as if I have never done this before and I have no excuses for the utter ****e times.

Cliff,
Bull****.... it's the winning that counts! roflol

Paul,
I seriously had no aspirations about beating the EVO boys specifically, but when you realise you should be doing so much better.... that's what pee's you off.

If it wasn't for taking the mick out of John and Mark I would of been crying!

It shouldn't be a big deal but it did spoil my day if I am being honest. As you say though, **** happens and I need to get back on the horse again asap.

Without doubt the cailber of drivers that take part in the MLRSS is very high. The event as a whole was very professional and very well run.

johnfelstead

I spoke to Richard last year about doing just that, but he didnt seem too keen on the OEM ECU using the MegaRom code and the plenum charge temp sensor together. I think he said you would need the groupN ROM file in there to make it work due to heat soak in the plenum causing the charge temp sensor to sense high when static, as the groupN ROM file code doesn't have any active knock control on it, it's not suitable for a road car setup with variable fuel quality.

I wouldn't be too down about Silverstone Shaun, it was a very challenging course to get your head round, having those tyres in the chicane and the new barriers meant you had to be pretty confident to get a good time, and the RE070's didnt give any confidence boost there, it was actually quite hairy trying to go quickly on those things, and i quite enjoy a loose car as you know. They were actually a lot worse than i expected, and if you remember beforehand i said they wouldnt be great.

Had we been on Elvington levels of grip with the RE070's on the same format of circuit you would have done a lot better i'm sure.

Hi Shaun, I know what you are saying and can appreciate you expected more from yourself, but it's your FIRST time out in this car and on ROAD tyres in competition, I feel your being too hard on yourself.

You know that once you have digested what happened and the emotions calm down this experience will be taken as a positive as to what needs doing in the future > and this is why you did what you did to your last car however learning the lessons from your last car and not going too far is a very difficult balance to get just right. Good luck fella

Shaun

Just reading back through the text messages from the 17th March John:

Shaun:"You doing the sprint at Silverstone?"
John:"Think so, need tyres ideally"
Shaun:"What for....it's only a Sprint!"
John:"Exactly, RE070's give no grip on that surface till hot. Won't work there"

I still suggest my gash driving was to blame but I understand what you're saying.

Anyway... onwards and upwards.

Shaun

I need to get back to Snetterton for some confidence building (I love that circuit) and safely discover what I and the Hawkeye can do.... being surrounded by armco and tyre walled chicanes perhaps didn't help knowing what would happen if I over cooked it. I need to grow bigger ***** like John and Mark.

Shaun,

well done on having a go ! At least it came home intact ! So you live to fight another day, and as in any past-time there is always someone willing to go a step further, budget permitting.

I choose Teins for mine which are too much for the mean streets of South Leeds, but worth every penny on track.

All you need is a set of sticky tyres and some more fuel. Go for it !

dunx

Shaun

Steve,
I did say goodbye to John as he was around just as the last runs finished.... you lot had scarpered somewhere and Mark was over the other side of the field!

You did really well for your first ever go on track, let alone competition stuff. You should be well chuffed with what you did.

Dunx,
It was nearly intact.... a front indicator bulb fell out (must of been all that tank slapping I was doing) and it took me an hour to get the headlamp out today to push the flaming thing back in! lol

I certainly need to get myself some more tyres and another set of rims.... I flogged my spare set of rims with the Spec C (which would be no good for this car anyhow) and the two sets of 888's I had.

It's not the budget that is/was the problem.... it's driving like a complete numpty yesterday that was the problem. Just to put this in to perspective, I wasn't that much slower when I did Time Attack on the National Circuit in 2006... which was just under a .6 mile longer and my first ever proper "blast" in competition stuff! Although I appreciate that Stowe is much more technical.

iTrader: (8)

Shaun, I got slated for the r888's and I can understand why as virtually every corner it was sliding on exit and changing from 2nd to 3rd kicked the back end out everytime

I have a set of khumo's which I have been told are superb but I'm saving them for SSO

Shaun

roflol - you should of tried RE070's if you wanted to see what "sliding" was all about!

Guess what tyre Mark used to shave nearly 4s off his times.... Khumo's!

I always found 888's OK at Elvington... as it's an abrasive surface. You might end up smashing those Khumo's up a tad there.

Good to meet you too Steve. Thanks for the chat..

Shaun

OK... back to the Project "stuff".

Spoken to Litchfields today and the new LM Billet Wheels are ready to ship/fit!!!

The car is booked in with Litchfields this Saturday and the plan is for me to pick the car up the following Friday. The current LM will be taken off, sent to Turbo Dynamics, th new Billet core fitted and sent back to Litchfields for fitment. I will then hopefully get Tracktive to remap on that Friday or the Saturday. All being well I will have some information on testing that weekend.

MelTypeR who has a LM450 equipped JDM is up at Litchfields this Saturday. He has kindly offered to let me have a drive in his car to see what I think of his LM450 (non Billet) turbo. I *may* decide to give the Billet version of that turbo a go, depending on how the test drive goes If nothing else it will provide some good feedback that I will of course give on this thread.

Based on some information Mel has given me (an unbiased view - which in reality matches what Iain has already told me) I already suspect I will stick with the Billet LM400, due to the fact that I am keen on driveability over increased outright power. However, I will remain open minded as the real world "feel" of the LM450 (which should only improve with the Billet version) may not be such a problem.

It will be interesting to see how this pans out.

Hi fella, ask Richard or Matt what they think of my car now with the LM420 and "MY" supporting mods, if your ever about when I am down there you can take it for a spin / sorry testing my car set up now is awesome, cant believe how much difference the FMIC and the cold air inlet has made, as Clarkson would say POWER

Shaun

Hi Lee,
I would have to see some real big increase to justify a FMIC and inlet change. If I did change to a LM450 and a restriction was being caused by either of these two area's, then they would have to be looked at without a doubt. Being practical the current LM400 already produces the power that it is rated at, so I don't see the point for road use. The LM450 might be a different story and what interests me about that, is to see how far I can push the OE inlet and TMIC towards that power level..... should that turbo be chosen.

I am up for testing and sharing my results, but I am not up for banging something on unless it is apparant it is required.

IMO for your intended use a FMIC is sensible regardless.

Toffee

iTrader: (3)

Hi fella,

My main statement would be "ask Richard & Matt" what they think, if I give my opinion it will be clouded by personal preference, the guys at Tracktive are fairly impartial. If they state the LM400 or 450 is better fine, but it would be interesting for you to hear what they think.

After my mapping session Matt stated the ignition was advanced bcause the cool air being provided was so much better that this could be done, interestingly Richard stated "Lee theres no more power coming from this without a lot of work being done" apparently my MAF sensor is maxed out > please bare in mind this aint a technical know how thing from me I am just listening to someone who knows what there on about which is why I stated ask them.

I am gutted I never made the RR last weekend so I could give you a graph to see what the power is like and if the LAG is much worse than the LM400, what I am certain about from what I am hearing is that the LAG may be very slightly worse but the pay of for my set up is a lot more power > more than the LM400 > LM420 would suggest.

Lee.

Shaun

Hi Lee,
I totally understand what you're saying mate.

I am here to weigh this all up and whilst I do not agrue that increases can be made, the question is at what cost. How much did you spend on your FMIC, Induction Kit and fitting? - That is my point for what THIS project is all about. Performance per £ and the real world impact and need. Don't worry... I know how to spend money. Been there and done that to the tune of circa £60k on the Spec C! It's quite a relief to take a different view on things nowadays. lol

The MAF scaling issue can be sorted, but as Rich says, requires a lot more mapping time.

On a side note... Rich is just as interested as me to see what can actually be achieved out of the Hawkeye TMIC and OE inlet kit. We do discuss what and how things may work and what would be good to try and test, in the same way as I discuss this project with Litchfields. Don't worry... the LM420 has come up in conversation quite a few times beween the three of us.

If it transpires that I do "go up" in size on the turbo, I will accept that there is a possibility I might have to fork out for a FMIC and Inlet kit. Until I make that decision on the turbo and then actually test it... I will never know. In part, this is also what this thread is all about.... testing and sharing the results.

Thanks for the offer of a test drve..... most kind of you Sir.

Fair enough Shaun the reason I commented was mainly because of your point of going from LM400 up to LM450, as you have stated you want real world power without the lag, however the extra power from the LM450 is always going to be a draw. This is why I made the point about my set up because it does offer good spool up on a 2.0L engine but with a fair chunk or power. Granted the full set up does cost bucks!!

I am gonna get it on the dyno to see where we are at, I would estimate now its around 435/440hp? we will see.

Good luck fella,
Lee.

Shaun

Hi Lee,
It's normally a case of compromise whatever you end up doing, but that is all down to a subjective view on what is best for you. What I want is not always what everyone else wants, however having the information about what can achieve what, certainly provides information for others. Your results will certainly be interesting as much as your on-going personal feedback.

I would be surprised if the LM420 is able to produce a true 440bhp, purely down to the specification of the wheel. It will be fantastic if yours is at this level and I (together with a lot of others) will be interested in your results. I estimate up to 430bhp... can we start the bets please.

Toffee

iTrader: (3)

I will go for 435hp / 385torx

Shaun

I suspect it will be more than 385lbft.... mine makes that and on a dyno that historically provides low torque figures.

Ilya

can't wait 4 the results with the billet lm400 shaun

Shaun

APRIL 2011
Right.... we are getting there now. The Hawkeye was dropped off to Litchfields yesterday for the turbo work to be completed this coming week.

Due to the fact that I needed to get home and I wasn't going to walk the 60+ miles, Iain gave me a courtesy car to borrow. I was quite priviledged that he gave me one of the most rare and best performance cars he has......... a Subaru R2!





LM Billet
As I have insinuated previously, I was starting to waiver on actually making a decision to whether or not stick with the LM400 or move to a bigger LM450 for this part of the project.

Mel graciously offered to allow me to test drive his LM450 equipped Hawkeye Spec C, as he had organised for some work to be done at Litchfields yesterday, when I was dropping my car off. It was a perfect oppourtunity for me to have a near as damn it comparison between the two turbos.

Mel had decided to have similar chassis mods to what I have done so far in this project thread (Whiteline Anti Lift Kit, ARB's and adjustable top mounts) and the first mod of the ARB's was just about to be done. We had a chat and Mel was unsure how far to take his ARB's (24mm rear or 22mm rear). I explained the differences to him in what it would change with the handling characteristics, but it made sense for Mel to try this first hand, so he went for a spin in my Hawkeye.

Just as I experienced upon having these mods, Mel immediately felt the difference in stability and sure footedness..... he was pretty much "sold" on the benefits of these chassis mods.

Anyway.... unfortunately Litchfields ran in to a problem with their four wheel alignment rig and they were unable to complete the work. This ultimately meant that Mel had to leave the car at Litchfields and I was unable to take his car for a test drive. It was a real shame, but I suspect "him upstairs" was trying to tell me something.

Mel did comment on the fact that his car gives him move of a shove in the back, but you have to take this in context as you would expect that with a turbo that spools 5-600rpm later than what the LM400 does (the "go" with the 400 is more instant and smoother). Add to the fact that Mel's turbo is producing another 40lbft and 60bhp more.... and of course his car is some 70+kgs lighter than mine. It all adds up to make a difference "feel" wise, but I certainly expect the LM450 to make for a quicker car when you are up to boost. However it is interesting that Mel normally uses his low boost setting (which is circa 380bhp). This backs up what I have said previously, in that 400bhp is more than enough for a road car and this is exactly where the LM400 is pitched!

I went on to discuss this with Iain and we decided that since this part of the project was "all about" the LM400 in reality and keeping everything nice and driveable as much as possible, we would stick with the LM400 Billet at this stage.

Don't despair though..... the conversation and agreement has been made, that once the LM400 Billet has been tested for the purpose of this thread, I have the option to move then to the LM450 Billet if I wish. Again, the "staged" approach has been favoured to realise the benefit of some worthwhlile feedback and comparisons.

I spoke to Iain about the changes that have been introduced to make the LM400 Billet and apart from the obvious fact that the compressor wheel is made of Billet, the wheel design has also changed, it is THIRTY % lighter than the current LM400 non billet compressor wheel and Litchfields have taken the opportunity to make the overall diameter of the compressor wheel smaller.

All these area's combined will theorectically improve throttle response and initial spool.

It will be interesting to see what transpires.

Hi Shaun,

Good meeting you on saturday, I think sat wasnt both our day at all really!!

Thanks for the quick run in your car mate, the smoothness of the power delivery of that LM400 makes it go even better then the stock twin scroll turbo.
So anyone interested in a sensible turbo upgrade without wanting to go silly bhp and the full hog of injectors and front mount etc... this is an option def worth considering.

Lol, 1 thing that did grab my attention the most in the test drive was the sound insulation that comes on normal cars , the cabin noise inside your car was noticably quieter to the point i didnt have to shout to you as im used to in my Spec C , the things we Spec C drivers put up with just for a bit of a weight reduction!!

Offer still stands to give it a test drive mine Shaun so drop me a pm.

Mel
