We are talking about 2 litre engines and a suitable turbo for a guy in Poland. Right?
As far as I know Steve McCulloch did 408bhp at Well Lane and it was NOT on a Lateral turbo.May have come from Bob Rawle-BRD, not sure but Bob certainly had a hand in it.
If you are referring to Alan Garrod then he has done 390 bhp and still has more to come from mapping of the car. It is about 9 or 10 months since he started on the hybrid turbo path and as far as I know this is the third turbo on his car in that time so it was not an out the box proven turbo solution from Lateral but in fairness I think his spec was for 350bhp and 1.5 bar boost which I would have thought would have been readily available off the shelf 9 months ago.
I am very sorry for Adam that his engine has been tested to destruction and the engine bed figures are really impressive even for a 2.5 litre but I do not see that this has any relevance to recommending a turbo to a guy in Poland with a 2 litre that he wants to bolt on to his engine and work from the word go.
I am sure greanade tuning is very exciting but it is very sore on the pocket for Adam.

Harvey my apollogies last time I spoke to steve it was.. I thought Alan was also over 400.. must be those dodgy ap22 results

Marcin I would speak to mark about your box first wouldnt go for the 6spd for drag racing, I would also get sensible?
When your on the phone have a chat about turbo's everyone has there own preferences.. You dont have to buy if you dont like

Also what autronics have you got?, have a look at the mode flags and turn on Antilag there are three options.. dont recommend the third unless you are mad

That's what I did - spoke about the box first
And I don't want a six speed anymore - but an earlier STi would be nice (for some time at least).
I've got SMD and started experimenting with the ALS/launch control so I expect some improvement here too.
Will also try to talk to AndyF.

Harvey, why do u say that it has been tested to destruction, AFAIK Adam requested more power, and the pistons/rod/crank could take the xtra power, but apparently the limits of a open deck EJ25 (although it was semi closed) engine were found.
This may well be an indication of what a open deck or even a semi closed deck Subaru block can stand in terms of torque and HP.

Thanks for the vote of support, Harvey, feel free to contribute to the sore pocket! The gasket was an issue by the way, and did its job well!

Just want to make it clear to anyone who may have misinterpreted, that mark of lateral performance had nothing whatsoever to do with the demise of my engine. I asked him, and Pat to be at the dyno as they have a habit of making sure the map is as good as it can be, and are better able to prod the dyno operator in the right direction.

The map was far from OTT. The boost level was chosen by me, as was the redline of 7500, and it was Mark who actually convinced me that I should NOT run more boost, "just" because I wanted to go for 600lbft.

This was not a lateral performance project car, but I started building it effectively copying marks spec, and over the months we have been able to refine it, and sort out potential issues.

His company is responsible for supplying the modified heads, rods, pistons, bearings, fuel pumps (all three of them) fuel filters, injectors, air injectors, air filter set up, gearbox, diff's, and without question and most importantly, the turbo.

Anyone who can't appreciate what a great choice of turbo it was, needs their head read. I no way expected 500+lbft from 3500 to 6000ish, but 561ftlbs, and 567bhp by 5500rpm, was incredible, even if the block did let us down !

I was a little disheartened to see the term "grenade tuning", the "injury" to the engine was no ones' fault, except possibly the US company who supplied the block. Boost was not ridiculous given the rest of the build, but I am glad to say I have a learned a valuable lesson which could otherwise have been very very expensive.

Mark used the term Adam2 on the 22b thread, I prefer to see this as 1.01.

Adam M

andy, I would if I knew what you were talking about.

can you explain then I might stand a chance of answering.

all i know is that the guy chooses an rpm point to map, then feeds in the throttle to allow the car to get there and overshoot, he then increases the resistance of the water until the revs "stabilise" at the desired speed. there is a feedback circuit which must have a pid controller for controlling water level.

Boost is controlled separately by a pressure line.

Pavlo

Andy,

To allow a meaningful comparison, please can you tell us how Star rolling road flywheel figures compare to this engine dyno?

Paul

Adam M

appreciate what you are saying, and I am also aware that the only way I would get that boost response on the road would be if i was towing a caravan.

so ultimately the boost wont come in quite that low.

I can hack that. if it means knocking 50lbft across the boost curve then so be it. I can still handle that (I won't be ablke to actually handle the car though).

Pavlo

I know what you mean andy, but I witnessed some of the runs, and the way the turbo spools up is frightening. I am certain Adam will see that power curve, or something VERY close to it in 4th gear. The biggest problem I think will be mapping the boost appropriately, or you will get an almost uncontrollable kick when it comes in.

But as Harvey mentioned, this is about 400-420hp...

Paul

moses

what harvey is this is it harvey gibb at peterborough

Pavlo

Moses,

Nonononono

The name's Smith, Harvey Smith.

Star of Banzai magasine Scooby dyno shootout thingy, and of course scoobynet and 22B BBSs.

Paul

moses

oh cheers mate this is the guy with the 2.5 stroker is it

and hows pavlo picasso today

Pavlo

I am fine.

My 2.5 stroker engine will let you know though, it might need to get a little attention.

Paul

moses

sure would mate i hope u take me out in it

and u can have a run in my 2.3 stroker and i wont tell u the power yet lets say its gonna be so freaking powerful i need a massive and strong rs diff with plates

Andy.F

Paul, that wouldn't be your turbo on there would it

moses

andy is it true is adams car gonna be faster than yours

Andy.F

Yes Moses, MUCH faster !!

moses

hmm i still wish u are the fastest andy coz your a down to earth ginger guy

Adam M

andy,

your car will always be faster than mine so long as I am behind the wheel of mine.

believe me.

R19KET

Andy,

There is very little load applied to the engine, until the boost/rpm target is reached. The rpm is allowed to over shoot by a few hundred, and then brought down to the target, and a reading taken. Boost is always achieved well before the rpm target.

Like Paul said, I think you'd be amazed at just how quickly the rpm target was achieved. Even at 7000rpm, it's only a few seconds, very much less than any RR run I've seen.

However, I would agree that "on the road", it may lose a few hundred rpm, but since it was able to achieve over 30psi by 3500rpm, even if it drops to 20>25psi it's going to be fun.

Just for reference, the 542ftlbs was achieved at 27.2psi.

Mark.

Carlos : "Tested to destruction" Is that not what happened ? I suppose I could have said `Tested till it broke` ?

Adam : I am genuinely sorry it broke on the dyno and hope the damage is limited but in my experience you will be extremely lucky if that is the case but I wish you well with it and hope you have it running soon. I am sorry you did not like my use of "Grenade tuning" but it sure is fun blowing engines up on the dyno and that is what I was referring to.

Adam M

thanks harvey, appreciate the sentiment.

Scoty

Well done Adam,

Truely a major result and another big step forward

Good luck to everyone who is doing similar work on their engines, this year and the next is going to be "VERY" exciting, as the word awsome and monster scoobs take on a hole new meaning

Andy.F

Not too many 'holes' though Scoty

nom-c-david wallis- nom again- .........and still no banner add!!!

you have got to understand that all these are people mark, at lateral, calls good friends.

rather than spending £1200 on a turbo that "claims" over 400 bhp send andy F an e-mail about his TDO5/6 upgrade.

this IS proven to over 400 bhp and costs a hell of a lot less.

i am yet to hear of an engine or turbo from LATERAL PERFORMANCE LTD that lives up to expectations.

if you want proven go for a turbo from Andy F, BRD or ion performance.

all in my opinion

Scoty

Can also vouch for AndyF's turbo's, as I have one fitted on my car.
(Mines isn't a TD05/06 hybrid and won't make 400+, but just thought I would support what Jonny has just said

Dougsters had a good days driving my car, and was also "VERY" impressed with the turbo.
ECU needs a re-map though, could only get to half throttle before hitting fuel cut at 25psi



Cheers Andy

jonny gav : the turbo mark supplied me produces over 400bhp and IS proven.

Obviousily you are blind- try opening your eyes and having a look!

christian, you needed a 2.5 to do it though!

we are talking about getting a 2.0 over 400 not a 2.5!

how much did your turbo cost out of interest???

......and wasn't it supposed to produce over 500bhp???????
