how fast can you go with the stock turbo?

what is the limit on boost and how fast can you go with a stock turbo?

 

[DCVING 6]

considering stock converter, injectors, etc.

Generally 22-23psi and 12.50-12.20.

Some have been faster with ported heads and such, but the norm seems to be the above mentioned numbers.

I have stock motor, turbo, 009's, 92 oct. chip, 340 pump hot wired, front mount..how fast should it go?

Without racegas or alky you are going to be limited in how much boost you can run... Tires and 92 octane, mid 13s. With race fuel or alky and chip, 12s easy.

what dose it take to have a soild 11.50-11.60 car?

 

[DCVING 6]

Solid 11.50's?

I'd say ditch the 009's and get some 57lbers. There about as big as you can go without the computer mod.

Say like a TE-60 with a 3000-3200 stall.

Higher timing chip, and race gas

bigger turbo, injectors, improved intercooler, traction, race gas, race chip, good exhaust (including downpipe)......and even then you will need to run very high boost

the most efficient way would be to port your heads and do the upgrades mentioned

the vast majority of TR's will never see mid 11's (12's are easy.......11's, particularly mid 11's, are a quantum leap more difficult

Mostly stock setup I had ran 7.7s, 7.8s in the eighth (lower 12s in the quarter), best of 7.74 @ 88 on 21 psi and 110 fuel.

Then I bought a car with good ported heads, smaller roller cam, and TA 61 turbo and it just ran 7.52 @ 89 (high 11s) on 18 psi and 93 pump gas, first time out. As mentioned, ported heads and the mods listed can run faster, even on pump gas, then a stock turbo on race fuel.
