Re: Would a blow off valve work?
90 percent of you guys really really really need to just look at a turbo car and would realize how it wouldn't work lol
this thread really made me sad about the knowledge of people in this community...
the main reason why a BOV is in place is to protect the turbo from air being pushed back into its turbines... if you close the throttle during a shift and the air bounces back into the turbines still pressurizing boost what do you think would happen?
If you realize where your throttle is on the crossfire and where the air actually gets pressurized you would understand that there is absolutely no effective way to make this work.
i am seriously disappointed. I thought you guys were old and knowledgeable.

Worked fine on my car, and I didn't notice any loss in performance!

If you really want a BOV spend $10,000+ and let Eurocharged turbo your SRT-6.
my $.02

a blow off valve is there so that when you are shifting gears and you momentarily let the throttle plate close the pressurized air has a place to escape (out the blow off valve / pressure release valve) instead of being slammed into the closed throttle body and backfeeding the pressure to the turbo which wants to keep spinning forward. that is on a blow thru TB designed car where the inlet (compressor) side fo the turbo is BEFORE the throttle body

Re: Would a blow off valve work?
Sorry fellas I got my information wrong,
What I had on my SRT for a short period was not infact a BOV but rather a By Pass Valve, my brother in law said it works like this
1. When you are NOT accelerating (foot is not on the throttle) the valve is OPEN
2. When you hit the throttle the valve would CLOSE
thus when the car was ideling or no throttle was applied you could hear a slight whistle, when you hit the throttle NO SOUND, when you release the throttle you get a LOUD gush of air (similar to a BOV) then it would resume to a quite whistle.
Now the way this was connected is as follows
Most of you have NW's CAI so Imagine drilling a hole in the NW CAI pipe now in that hole one of the "by pass valves" hole fits the hole you made in the pipe then the other little tube comes from the engine into the "by pass valve'" like a little vacume tube.
I hope I've explained it right, any questions or comments? fire away!

argh... i know its just the internet and not every one know everything about cars i know i sure have more to learn.... but dont spread STUPID bogus FALSE information about something you havent even the slightest clue about on this forum!

Re: Would a blow off valve work?
LOL that was really funny i actually laughed out loud. How old is that report early 90s? Anyone here have a copy of Forza Motorsport 3? The SRT6 is in the game, Great simulation, you can extensively modify it and go on real world tracks, 1/4 and even throw a AWD system into the car, its nuts, if you have a Xbox i suggest you get a copy

LMFAO! That is the first time I ever saw that video. The best part is at 1:49 when they almost side swipe another car and then run a stop sign!!! Classic!

Re: Would a blow off valve work?
Hey Dylan
No i didnt see your thread on FM3 im going through it now though.
As for the speed ratings i never really buy into it, ive made the 6 faster with a worse speed rating. Race the c32 u will beat it. Try this. Convert to AWD, adds on 100kg and it lowers your class level substantialy. Add some power mods to the same class level it was stock and u will have a faster car with better handling

Re: Would a blow off valve work?
Yar, of course you can mod it to the same level. Just disappointing that hey don't bother to get things even roughly correct from the outset. Also the several obvious model innacuracies that could have been avoided by just looking at a PHOTO are not something that the Gran Turismo guys would have done.
