what's the highest you've safely gone on stock internals

i boost at 9psi but im rebuilding REAL soon. ive gone as much as 12psi at the track ONCE just to see my times.

I hit 20 PSI once, because i had incorrectly installed my wastegate. No problems for 8 months after that, either.

How did u incorrectly install ur westgate Dino??? lol. I just don't see how that can happen? :p

i've hit 15 before (only once) right after i fixed a boost leak i had and was testing it out. i forgot to turn down the mbc.
but not problems

Easy: the DeltaGate has two ports. I used the wrong one and boosted the sucker shut.

lol u crack me up man.
u still have yours dump into open air? just thinking of mking mine go into the down pipe. Just not liking that loud ass no muffler noise it makes...

Mine goes back into the downpipe, last bend before the cat. Cost me $50.

hey dino got a pic of how your wastegate tubr goes into your downpipe? I'm taking mine to a muffler shop real soon to get mine done, and i wanted to have a pic i could show the shop guys, so they get it right

Uhh.. look up one post ;-)

I've hit 10 psi before and run 8psi daily....just at 10 psi i get this studdering feeling that I don't like....Like there is not enough fuel going in so I just don't go up to 10 anymore....:( but 8 daily is running strong right now...

Does anyone have a better explaination to why my car studders at 10psi????? cause i would really like to know...thanx.

Probably for the same reason mine stuttered when my wastegate was boosted shut.. extreme detonation combined with pulled timing and misfires. Still can't believe i didn't blow it up then..

So if I put my cam gears in....maybe retard the timing a bit....then get a MSD ignition I should be ok for the time being????
