When does it hit full boost

When does it hit full boost

starts 3500

full 4700

[R31Nismoid]

Maybe your dyno readings are all low AND Incorrect. Ever thought about that?

times and power match over here... they dont often over there

[R31Nismoid]

starts 3500

full 4700

Question, is that with the bottle, or without it?

[MR331307]

without

i think it comes on about 3300 with nos and full at 4300 or so

when i get the ecu back

ill post two dyno sheets

one without nos and one with to compare

Thanks mate

if i can organise an auto or dog box

i will gain .7 of a second

to start with from what we calculated in time losing while changing gears

then a little more power and harder launch should run a 9

well what im aiming for anyway

2 weeks he says! i have witnesses now

Why did you need to borrow number plates?

[BezerkR32]

compressor surge is caused when your cylinder head cant flow what is being pushed through it. camshafts are your answer. GT35/40 are rated for 700hp.

Just a quick question, you say you have a gt3540 - just wondering what specs as mine has the 0.82 rear and is making 480rwhp with slight compressor surge (meaning the turbo has run out of flow) and 24psi, mine also sees full boost early 4000rpms - just after a comparison with when yours sees full boost as im assuming you have a 1.06 exhaust

And congrats on the power and qtr time

Does that mean you think 10.8 is as fast as it is going to go with the standard gearbox?

cheers

i think that is

if i flat change i think it will blow in the first couple runs

i am trying to find a dog box if any 1 has 1 for sale.

I was of the impression compressor surge meant the turbo had run out of flow capacity, GCG apperantly do an anti surge front cover which has small holes to help with flow. I am thinking of doing this and 66mm front wheel if it won't make it noticeably laggier

[paulr33]

according to garrett's site compress surge occurs when the pressure past the compressor outlet is greater than the pressure the compressor wheel can supply, ie the compressor map dictates that it can supply 12psi compression in the ideal scenario in the compressor island, but for some reason the pressure past the outlet, in intercooler/manifold pipework is above that 12psi level

They are bypass holes, they don't increase the maximum flow capacity of the compressor. They are used to prevent the problem that paulr33 explained in the previous post.
