I am wondering what the boost is on a stock firefly or sprint turbo.

Thanks.

Have you read the T3 supplement Jess? It says that the maximum pressure allowed before the wastegate opens is 10PSI, so I'd imagine thats for when its cooled. Why it does that I have no idea...

stock is supposed to be about 7psi, but you can use a bleeder to get it up about 10psi without any other modifications.
beware of cheap boost gauges, they often read higher then they really are, which is probably the safer route to go anyways.

so my autometer phontom gauges aren't very good? i thought they were allright, how do i confirm my current boost. my boost guage did read 7.5psi when i first got it, but then some strange spring showed up on the outside of my wastegate :wink: and i noticed i had 10psi. shortly after i removed the spring and it stayed at 10psi.

When I put the 2" exh. on my Mk2, max boost climbed to 10psi. After all the mods on the Mk1, it still runs 7.5-8psi max. I guess everyone is a little different.

not a cheap gauge at all, the spring makes sense, but without it ? that's kinda odd :huh: it's pretty rare for mechanical parts to 'heal' themselves or go stronger after having a bit of a rest.

lately it has been very cold in calgary. to the point of my wastegate constantly freezing shut. obviously i know to keep my foot 'off the floor' but it is just too tempting to see how it reacts at higher boost levels as my boost controller isnt in yet. the car seems to shake violently at 15psi, but it handles 12psi very well. i havent seen i it lean out at all either and you can accualy feel the extra power over the 9.5psi i am running now. only problem is that the -30c weather means a ton of ice on all roads. so i have all this extra power and no where to use it :cry:
but hopefully soon i get my new tranny and boost controller put in.

Aren't you pullin' the tranny outta my firefly? When I drove it for a couple minutes, it was so smooth compared to my tranny, I was seriously considering pulling it before you showed interest.
