Turbo ... What rpm should I shift at??

[killswitch06GT]

I have a 06 with on3 70mm turbo on 8 psi. I've been shifting at about 6k rpm but not sure where I should really shift. What are you other turbo guys reving to?

Depends on where you make power, where's your dyno sheet

About that.... Had it tuned by Lito I've yet to hit the dyno. Just curious what ppl with a similar build were doing.

Keep it at 6k rpms if your on the stock block, 6-8psi with a turbo is alot of hp/tq. Dont want to send a stock rod through the block by revving her up too high.

Will do. I'm so anxious for that aluminator now!!!

What about hwy pulls? What rpm, gear, speed is best? Not trying to hijack the thread but I think this is also important. Congrats on the turbo, can't wait for mine to be done.

I shift at 6k while my limiter is at 6800.

Np I'm interested to hear as well.

Not sure what you by highway pulls?

 

[killswitch06GT]

It really annoys me how weak our rods are... Other than the rods are there any other weak spots? I hear the crank can handle 700whp. I'm Half hearted to just throw in some h beams and a kellog crank and just go.

 

[JoshK]

Dont wanna use those hyper pistons for high boost. You have to have the whole engine apart to do rods, do it right the first time

I wouldn't do any WOT pulls in 5th gear eaither

I think hes saying what gear and speed is best to make a pull on a highway... That's what I'm getting out of it... Say like if u happened to run I to a goat that wanted to play ??? Hah

Why not in 5th?

 

[JoshK]

5th gear puts huge amounts of load on tnose weak rods.

 

[killswitch06GT]

That's even after shifting from 4th at wot?

 

[JoshK]

What speed are you at after you top 4th and go into 5th? I feel i am going fast enough before then on the street, and a track isnt that long. Maybe its an urban myth, but i dont have a need to go wot in 55h and dont plan to

 

[stkjock]

Yes, u lose the mechanical advantage of the gearing

 

[ctt326]

I'm around 120ish at the end of 3rd gear WOT and I won't go faster than that on the highway.

 

[Saleen S281]

I meant if you happen to be in Mexico and a Vette wants to go @60mph. I wouldn't think you'd deep it to second, more like third at 3500 rpm right? I know it depends on gearing too though.

 

[Mustangsam05]

That's when you use brake boosting
