curious what kind of boost you guys are seeing on 'stock sized' motors and at what rpm's making what kind of power?

anyone only using this turbo at acceptable stock bottom end boost levels?

i'm playing with the idea of foregoing a big NA build and doing a low budget (all work by me) stock bottom end single turbo IC truck manifold setup, on low boost (7-9psi, yes i have restraint lol). until i build up a decent shortblock then turn it up to 14psi or so.
yes i've been using the search feature and continue to do so.

 

Stock 93k mile long block in a Silverado SS. Full boost at about 3300-3500 depending on boost level. It comes on fast when you have it a 17psi lol. Truck went 11.8@119mph@5880lbs. So its make roughly 750-800fwhp I would guess, works great.

 

nice, thats a heavy hitter!
any input on it in a lighter 4th gen at lower boost levels?
i imagine the BB upgrade would lessen spool time by about 4-500rpm or so?

 

i am getting ready to put one on with a sts kit. i am changing the A/R out to a .81 to help with spool since i am a stock motor for now.

here is a thread on another gto car with that turbo.

oh, and what local are you out of? i am out of 915 tampa, fl

 

hey brother, i'm out of 196 Elgin, IL.

what was the original ar you had picked?
keep us posted on how your setup turns out! sounds cool! and thanks for the link.

 

.81 should work well with the rear mount, I would stick to the .96 with a front mount though.

 

you think the BB upgrade would be worth it? and is it a comparable BB upgrade to the Garrett cartridge?

 

No not at all. A couple hundred rpm is not worth the cost at all.

 

thats what i figured also, just good to hear other opinions.

so anyone running this as a front mount in a 4th gen want to chime in?

 

full boost by 4grand if i jam the throttle in gear at around 2grand

 

Josh, what A/R is yours?

 

.96 A/r

 

what about these turbos make them so much cheaper then the standard units?

I figure two TC76MPS would owrk good on my setup... lol

 

if its more then 346 cubes then i say go for it

 

it is.....just questioning the construction of this turbo

 

well i juts bolted mine in and ran the oil lines and so far not a drop of smoke or oil. thast all i could ever ask for

 

Tiago engineering house price break..... ...lol

They are the same construction as the rest. Same bearings, same internals......yadda...yadda

 

ran two on my 402 vette.....awesome turbos. .68 ar's and full boost by 4200.

 

What did they run on that 402?? Where did you purchase them?? Is this on a street car??? 4200 rpms is quick with a pair of 76's.

 

Probably. I have a pair waiting for my 427 if it ever gets finished.
