psi --> power

[hippy]

i got 33gtst, i was racing with a friends 180 .. it has similar mods, pod, exhaust and he also had afm which i don't ... he is running .8 bar which is standard for a 180, thats 11psi?? theres something wrong with my boost ... mechanic said theres a leak somewhere and its only at 6 psi ... now what i'm wondering is how much more power would i get if i fixed it and set it to 8 psi??

he beat me by a couple of car lengths, i tried to beat him a couple of times but its too slow ... could i beat him if i fixed my boost problem??

or rather .. how much more power can i expect from an extra 2 or 3 psi??

Fix your boost leak and chuck it on 8psi and let us know. Their is no handbook that tells us what can beat what.

he has a afm but u dont???

mean he has a z32 afm and u have the stock 1?

if hes got a z32 afm and is running stock turbo and about 11psi then hes car would be running shit, as u dont need a z32 afm unless u got bigger turbo and running alot more boost!

And more boost doesent always mean more power expecially with stock cooler, turbo. Its all about tune!

what i meant by that was that he has one of the apexi display things .. it wasnt a the boost controller but that avr thingy ... oh i dont'know .. i always get confused ... avr avc ...av something ...

:lol: avc-r is a boost controller!

and a boost controller wont give u anymore power unless u actually run more boost with it.

maybe he is talking about safc?

i know ... 180s are heaps cool ... he is going back overseas and will be looking to sell ... maybe i should sell the skyline and get the 180 ... its one of the new ones with skyline lights .. sell for about 15000 or so ... hmmm tempting

i know its a bit off topic, but if a person person had a boost leak, how would you go about and fixing such a problem;what things would you need to check or replace?

check all the rubber hoses off the actuator, boost controller for leaks. Also check that your IC piping is not loose.

[hippy]

well i haven't done it yet .. i'm just too lazy to bother about it hehehe .. but i suspect that the intercooler might be loose ... i haven't had a really really close check ... also i can hear this small sound as if air is leaking around the engine sometimes ... is that normal?? like if u leave ur engine off for a long time .. say couple of hours ... is there any sound around ur engine??

[Guest INASNT]

air leaking noise in engine bay would not be normal.

[hippy]

yeah i didn't think it was normal ... then i turned the engine on and then off and the noise was gone ... strange huh??

[hippy]

since ive not got any numbers yet ... how much powerloss would u expect for an average skyline with average mods say .. pod exhaust ... if u put the boost down 2 psi??

[Guest INASNT]

how longs a piece of string??

every car is different, its 2 hard to just say!

[hippy]

ok ok i get it ... nothing is certain in this world
