The 'blips' at 3500rpm I presume to be slip ? The kink as it approaches peak torque at 5700rpm is also slip I believe.
Switch from low to high is at 4300rpm. I need a 'proper' boost controller to iron out the notch that occurs due to the wastegate slamming shut then opening again as it switches over !

Also notable is the power is still rising as it is shut off at 7000 rpm !

 

Yes I am all to aware that your car is made from OEM parts so all credit to you

I understand this was nothing to do with lag - every time it hit one bar, the Samco inlet pipe collapsed due to the vacuum level and the gasflow significantly tailed off - that was in a previous life of course - it has all changed now

I thought you meant at WL4 that the 1 bar boost was being achieved, (that was before Christian posted his data)
Of course now I'm confused how the power is not higher with that level of boost on a 2.5 ?

 

Hi Christian: I know that you are very happy with the car on the road and obviously it can pull more boost than on the rollers, but now that I have seen your power figures for both Well Lane and Power Engineering, then like Andy, I am wondering why they are a little low in comparison to the latest 2 litre performers.

Is the turbo properly matched to your 2.5 engine ? Are you running the same turbo and headers ?

 

Simon, where the hell has the delete function disappeared to?

Compressor map looks appropriate Should support 500bhp/450lb-ft at 1.6 mid and 1.4 held on a 2.5Ltr
I 'presume' the turbine and housings are also properly matched ? If so, where's the power gone ??

 

AAAAAAAAAAAARRRRRRRRRGGGGGGGGHHHHHHHHHHHH

I've finally had enough.

Enough crap, enough insults disguised as banter, enough power claims, enough excuses for no power.

I'm going to buy a Nova

Paul

 

Paul,

If your going to buy a Nova there was a guy on here recently who could do sub 11 sec 1/4 miles in his, perhaps you could get the same spec as his and then you would know what a real performance car is

Could you also mail me a price for a set of 550cc injectors and also the adapters for phase 1 rails.

Andy I can feel you hitting 450 BHP soon and if you are ever coming down to PE let me know.

Cheers Colin

 

LOL @ AndyF: "low boost setting drops it to 375bhp".

Now that's just rubbing it in!!!

Awesome power!

 

andy or christian, what are you running to get those power figures from standard internals. ie what mods to your car

cheers

 

Andy,

It's quite simple really. If you use the same calculations to "estimate" Christians power, based on engine capacity/RPM/boost, as you do for the compressor maps, you'll see why he's getting the results he's getting.

Then you can do the same for the 1.8bar Christian said it was holding on the road.

Paul, I'm with you

Mark.

 

Andy

Fascinating thread to read. Congratulations, I take my hat off to you. Looking forward to seeing how far you can get it.

Les

 

Harvey,

RE your question: "Christian" ... "I have seen your power figures for both Well Lane and Power Engineering, then like Andy, I am wondering why they are a little low in comparison to the latest 2 litre performers."

It occurs to me that one thing that I haven't seen talked about very much with regards to these engines is compression ratio. Changing the C/R would certainly affect the engines power output characteristics. Are all the 2 Litre cars you are comparing to Christian's 2.5 running standard compression ratio? If not, what compression ratios are they running?

These 2L beasts are producing very impressive figures, especially Andy's OE parts special. I am just guessing that the C/R may have been changed from standard in some of these motors, and this may in some way help to answer the question you posed above.

Cheers,

Moray

 

it is quite obvious that cars are driven on roads/tracks and not at rolling dynos ..... so why don't you guys go the old fashion way and go to the pod or a track with a decent straight, or some "non public road" and do some launched starts, rolling starts, etc.

 

Si, I think you will find Christian is not on std internals....lol

My engine spec

Sti 4 pistons
STi head gaskets
2" Scoobysport uppipe
Twin dump Falkland downpipe
3" Jetex system
K&N filter and direct feed
Front entry WRX inlet manifold
550cc Mazda RX7 injectors
Parallel feed fuel supply
FSE fuel regulator
Lateral performance uprated fuel pump
FMIC (pace cores)
Minor head porting
Standard WRX cast headers ported
Standard WRX closed deck block
Standard WRX cams
Standard WRX rods and crank
Standard WRX ECU
Standard WRX turbo with bolt on 20G wheel and cover

Approx £1600 would cover the parts fitted but not my time !!!
£3.70 per bhp

cheers

Andy

 

Is also with Pavlo.

Scoobynet was fun - now it is just snidey crap.

Trout

 

Andy,I'm sure you've mentioned this before but what type of engine management are you using?
David(Trout),I d'ont think people are being snidey but their knowledge/hard work has been used without acknowledgement.They also run businesses and so are'nt prepared to share all their 'secrets'.I think thats fair.

 

.

 

Deep - I still have the original standard ECU in the car.

With the assistance of Pavlo we are hoping to have a suitable remap for it shortly.

PS What is everyone getting so upset about I certainly have no secrets on here, I regularly post my latest findings.

I also can understand and respect why those with a commercial interest are not so free with their information.

If someone spends a 'LOT' of time and money and doesn't get the results intended then is it a sin to try and help identify the reasons ?

Andy

 

Andy, I think people are upset by the underhanded comments aimed at insulting others, rather than just coming out with it.

I completely agree with those getting upset.

this is nothing to do with secrets, just the way people are choosing to have a pop at eachother. I am one of the youngest here, but it seems many others are far more capable of rekindling their playground days.

I wish people would reme,ber that we are all enthusiasts here, some making a living from it and some not, but all after the same goal, ie bettering our cars and enjoying them at the same time.

I cant believe so much of the scene has become so personal and the them and us menatlity that has been forming is really pathetic.

I am seriously losing interest in posting on here as a result.

 

Adam - You've got mail.......

 

Hi Steve

The front entry manifold will not give any more power, I'm of the opinion that it reduces lag slightly due to the shorter pipe runs to the FMIC, others disagree.

I have a spare TD05 but I'm using it to experiment with turbine set ups on my own car at the moment. They can generally be had in good condition for under £200 from a breakers but will need either a 16g front entry cover to suit your car (£70 ish) or a 20g upgrade kit (£300 ish) if you are aiming for over 400bhp

If you're in the states, you could pick up a brand new TD05 for US$675 ! A brand new 20g hybrid like my one will set you back approx $900. Just need to convince them it's not a bomb in your case

If you're interested, let me know and I'll give you the part numbers

cheers

Andy

 

Andy

Thanks.... USA.. back Thursday.. land on the Friday! so I can attend the RR day at PE.. on saturday!

Sorry you lost me ... what is 16g or 20g??...- is this like sending your turbo to Turbo Dynamics for a modification?? or is this a fitting type kit

Part no's that would be excellent.. e/r on tourist amount is $1.60.. and a little higher on c/c.. (with Nationwide!).. may be even better if they start a war.. should go to about $1.80!

Know any companies I can order from. Might be just as easy to order direct from Uk.. the US Airports are very, very strict about everything now so I dob turbo would get through.. although I would not want to pay duties, etc, either....

over 400bhp.. I want a turbo that can flow about 500bhp.. thats my aim.. then I can move on to another car......

I suspect the PE run may be a waste of time, as I have a smaller turbo and no headers on at the moment compared to Bob... will see just how restrictive the VF22md195 is.. that said it should be good for at least 400bhp...

Oh.. dont have time to go to breakers!...... sacrificies, sacrificies.. I dont have time to do anything to the car!!..... I am now starting to get very frustrated..... being over here in Illinios and Ohio.. have not come across any decent cars, except the Occasional GT2 911....

 

The 16g / 20g relates to some component sizes within the turbo. probably too much infomation for your thick scottish skull
Loosly translated they are 'go faster bits'
My current turbo I only rate to approx 460 bhp too small for you I guess ?
The upside of this is that there is 1 bar of boost available from 2800rpm which makes it very drivable and responsive. Depends what you want to use it for.

I'm not (yet) in a position to personally recommend a spec for a 500+ bhp turbo but I'm sure there are others who can.

cheers

Andy

 

Harvey,

" am wondering why they are a little low in comparison to the latest 2 litre performers."

You can already see that my torque figure is in another leagure compared to a 2litre. Bob was making 390ft/lbs at 2.2bar on the pe rollers. I was making 384ft/lbs at 1.4bar (peaking at 1.6) on the pe rollers.

 

To Everyone

I believe that this thread has run its course, and as such am locking it.

Guys, i am really dissapointed by the bickering that seems to be going on on here at the moment, especially as it is predominantly coming from respected people.

If you dont change your stance, then i am sorry, but i for one will not respect you for your knowledge, which is very sad really. I am sure others will feel the same too.

Could we all just chill out, and continue to help others on this BBS, instead of hindering them.

Thank you

Steven

Andy,

I thought this may help with the speculation about Christians turbo.



To convert lbs/min air flow to CFM, divide by 0.069

Mark.

I'm with Carlos here Roll up, roll up

Mark I wasn't having a dig. Just that a steel/forged internals 2.5 running an appropriate turbo and 1.4 bar held boost should be making MUCH more than 400 bhp by my calculations ? No ?
(Christian stated his car only held 1.6 bar on the road with a peak of 1.8)

Moray With the exception of Bob (who I have no info on) I do not think any of the 400+ 2.0 cars are running over 8.5:1 CR
My own car is running slightly less compression than std due to the sti pistons not protruding so far out the block.

Well, there is another bbs, although it is still viewed by others im sure, but doesnt get as many plonkers posting on it...
Perhaps some of these more interesting threads could be re-located there.
