this time ran out of mapping time @ 2:00am this morning
them track n road chaps are nuts lol.
a small actuator issue that we didn't have time to rectify resulted in only reaching .9bar and 313bhp, looks promising tho (again lol)

 

Nearly there Lee

When are you going to be going back and actually running some boost?

 

just bolting the flux capacitor on as we speak

 

getting there

 

how big is your exahust housing?

 

.86. which i don't mind the late boost, it was just that the actuator was weak or not pre-loaded enough to make more boost

 

300 +bhp on a bar boost

 

very late powerband compared to a cossie, like kinda like a GT35'd 600bhp style one

great power for .9bar on a 2litre tho

 

wow 300 bhp on a bar.... more to come then

 

what cam profiles are you using now? what they timed to?

 

great figs there

 

Depends if the spec will allow it to run any more boost though .

 

You can always run more boost mike....

I just might not be worth doing it LOL

 

Not if that boost leads to catostrophic det, there's only so much ignition you can pull out before the turbo / manifold melts .

 

As I said - it just might not be worth it - or intoher words everything melts lol

but its only running low boost atm and at 150bhp/l its nothing specail.

Alex

 

He can certainly run more boost, what remains to be found out is exactly how much more though.

 

2 bar would be interesting.

 

Define "interesting" .

 

I wouldn't expect too much more in all honesty, the torque is dropping off as soon as the boost is coming in

 

interesting

adjective

1 Someone or something that is interesting keeps your attention because they are unusual, exciting, or have lots of ideas:
She's quite an interesting woman.
She's got some very interesting things to say on the subject.
It is always interesting to hear other people's point of view.
Oh, I didn't know they were married - that's interesting.

2 HUMOROUS strange or different:
That's an interesting looking hat you're wearing, Neil!

 

 

the cams do need dialing in, it was intended at the mappers but time constraints so i'm hoping dialled in cams will reduce the torque falling.

 

there is low enough C/r mike to go with more boost before the det you mention (i hope)

 

xe cams gareth, i think 260 deg unsure on lift, deffo not dialled in , (just thrown in ) was hoping for them to be dialled in at the mappers.

 

Fingers crossed for you this time, as it would be good to see a number starting with a 4 .

 

.....bit like seeing your mental age Mike

 

I'm sure Steve and Steve will sort you out Lee.

 

i believe you would have a faster car if your reduced your exhaust housing

 

If it's making good power at just under 1 bar, then providing det is not an issue then 2 bar WILL give good results.

 

Looks very promising Lee well done

 

It doesn't work like that .

Let's use an Escort Cosworth as an example, at 22psi it makes 330bhp, by your logic running 2 bar into it would give a "good result". The reality is that running 2 bar through an Escort Cosworth without lowering the c/r would see it end up in moltern pieces scattered inside the engine bay .

I REALLY hope Lee has lowe enough compression to run the amount of boost that he needs to achieve 400+bhp, otherwise I know he will be disappointed .

 

Really?
Then how comes one of Mark's escorts on Autronics with standard comp ratio and t34 made excessively good power with 2.3 bar. Like i said, if det is not an issue then why wont it be good?

 

mike my car runs 2bar 12 degrees of advance on 8:1 compression

 

bad example i think mike,,, but yes i agree with you,, it doesnt always work like that!

flow and pressure are two different things,,,,, but if you can flow any more though the pressure simple rises

 

GARETH T

What i am trying to understand is this;

You can run 2 bar+ through a standard comp cossie engine (example picked by Mike) without having melted internals. You are a good example of this are you not Gareth I have no idea on the igntion advance side of things, but a mapper does and hence yours is safe yes

So why should it be any different on a cavalier?

 

There is no way I would want ignition that retarded, it is fine for a road car, but the heat it generates when "on it" is horrendous .

Personal preferences, but I would always rather run low comp / lots of ignition and boost than high comp / loads of ignition pulled out and high boost. The latter (on a Cosworth) leads to thermal problems that would mean the car could never be held flat out without the engine shitting itself.

Perhaps to prove my point, you should max your car out Gareth .

 

Mike Rainbird

So what i said is actually correct and can be done, regardless of your feelings of high(ish) comp engines and holdng them flat out. Shame on you for trying to dis-credit a MADette just for the sake of it

 

12 degrees

 

Rich,
Evo's run MINUS ignition values in certain circumstances (but different bore / stroke to a Cossie, so not directly comparable) and Simon actually used to run SINGLE figures on his (but melted several engines ) with an MD240 turbo.

Ask Euan what ignition HE runs on the top line and then look at how reliable his engine is at 2.5 bar, compared to say - Aides high comp one.... .

 

12 degrees isnt that bad,,,, my egt's dont go too high,,, whats the problem?
