high comp and boost

[9Deucelx]

devin you better have a perfect tune then....as said earlier even the smallest hiccup could with that high of a comp. ratio....it might help if u read some more on turbo engines en stuff before u start this project 2 see if u really wanna boost ur car

[4doorkiller]

just out of curiousity Devin: what setup and powerplant were you planning on running anyway?

[Devin]

Not quite but there are exceptions. Given the same scenario but with a higher compression engine with smaller boost the output could be the same if not within the same range as the engine running lower compression with higher boost. It is power that should be concerned and not psi level. And yes margin of error for tuning is decreased.

well guyz i built this engine 7000 miles ago but the power is not what i expected from high comp and i need more i live for this shit

[d112crzy]

i agree d11 tuning is essential with n e kind of engine build..but wouldnt a low comp. engine make more power than a high comp. on the same boosted engine?

if yuo have the same setup on both and the only difference between the two is the compression ratio, the higher compression ratio will make more power.

You don't always have to boost a motor man! ITB's! I would if i were you! I haven't seen an ITB'ed accord yet on here. And it about the same if not cheaper then boosting your motor (depending on how you do it)

[d112crzy]

cheaper....only if you do it yourself.

more power...about more than 50% of the time, I can get myself a boosted setup and make more power than you would with ITB's with the same amount of money spent on both cars.

either way, for ITB's to even start serving their full purpose and actually make it worthwhile, you would have to get high compression and do tons of other work.

THAT is not cheap. also, good luck tuning ITB's, especially if you're a beginner.

2point6 has/had ITB's. look him up.

[4doorkiller]

i heard in order for ITB's to perform their best it has to be a hot and dry day. anybody know if this myth is busted or not?

[lokuputha]

It should all depend on the tuning level...if you go with very complexed maps...u should be able to get it right...I have a friend that has a VW with 12.1 compression with more than 16psi of boost...i mean that is sometimes diesel territory

First i never said anything about more power. Second boost on high compression will cost more then a ITB setup ( you will blow head gaskets all the time) Third he already has 12.1. Tuning with ITB's is just like tuning a bike or a Carbed car!

[d112crzy]

tuning a carbed engine is by car WAY easier than tuning with ITB's. Especially if you have the no so expensive EMS.

if you blow head gaskets all the time, you're obviously doing something wrong.

[h33lt03]

I am just going to say this high boost high compression= horrible idea.

Realisticly High boost low compression or high compression low boost choose you weapon

lol blow head gaskets...These arent MKIII supras. Anyway 12:1 would require some damn good fuel. I would go around 11:1-11.5:1 for boosting if your gonna do it on a dd. Plus there are ITB turbo setups. That teggy video boosted ITB 11.5:1 compression bitch responds like a mofo. YOu can try that bio fuel that might allow you to run the 12:1 compression ratio. Oh yea and your high compression + boost = not a good idea....thats only true for amateurs that dunno how to tune

[d112crzy]

e85, that is all.

[NAiL05]

e85, that is all.

Thats the fuel im talkin about. A couple people around dallas have been tuned on that. Some dude is pushing like 450 or so on his ls vtec turbo. Forgot the exact spec but I gotta look at it again. He says shit pulls hard the future of race gas =D.

Agreed, enough said.
