compression ratio vs boost psi

[ZeForce]

Im pretty sure thought. All factors equal.

Both High comp and low comp tuned to the same point before premature detonation. High comp will never have as much timing... & Timing makes the powa!

I disagree with that, the more you advance the timing the more the engine is working against itself

[Sexc86]

only after a certain point will you increase timing so far that you wont net any futher power... you will only increase combustion pressure. So Yes and No to your opinion. Everything has to be treated on a case by case basis imo

I dont think this will ever be agreed on, as i just read all 15 pages and for the whole lot all the ppl with high comp engines say its the best idea because you dont get as much lag but all the low comp say yes bit more lag but safe.

I think its always goin to come down to what you want from your car,(my thoughts) if you want more of a N/A car with boost and dont care abt big numbers then high comp.
but if u like to boast abt ur car how it runs 1,000,000 psi and u have a turbo that resembles a black hole on your car and want massive numbers and dont care abt lag then low comp.

I personally am goin low comp as I have ERL building me a b16 race short block that is rated to 800hp and 40psi with 9:1comp and my logic is if you want response stay with N/A and that a honda engine has a massive rev range so unless your dragging off the lights or at the strip, just down shift.

[DLO01]

I wouldn't class 9.1 as 'low compression'.

[Limbo]

i have high comp and i still have lag.
Its just depends on how much of it you have

[markoJEK1]

Of coarse youre going to have lag, its turbo'd and lag varies on its size and the engine capacity, what people are saying is that NA Honda motors and their high comp, dont have that piggish feeling down low like motors which are built for high psi and are low comp, causing them to be nearly useless off boost / down low.

High comp = more driveable / repsonive off boost

So for a daily / fun car, high comp low boost, you get best of both worlds, (ie: VW making their TSI (turbo superchatged injection) Polo, got the benefit of supercharger down low and turbo up high, to eliminate any 'flat' spots in its driveability.

Low comp = sluggish / boring imo off boost
Not as ideal for daily / will make big numbers

Thats the main thing you need to convey from all of this imo , alot of factors playing a role of how a car will be if turboed.

[lookingforboost]

but which one off the two produce the most torque in specific to hondas?

[Sexc86]

Boost produces torque.

Low comp, More timing, more torque, more hp, more lag

[lookingforboost]

hmmm its a real trade off really....
