What is better innovative t-66 dual bb or the gt35/40?
And what specs for 13b-rew on the t-66,a/r,trim ,and other specs.

housing,spooling,top-end,Horse Power

 

I'de be very interested in knowing what other people think about these two turbo's. I just ordered a GT35/40 kit.

I'm not sure if anyone has enough experience with the GT35/40 to do a real life comparison ... I hope to be a ground breaker...and post some dyno sheets...

this is on the t66bb

GT66 will mierda on the GT3540. Contact me for info. greg@fcpower.com Pricing is high but well worth the money. i just ordered a few gt60-1s for a few guys and I think thats a more comparable turbo. The real question should be "GT60-1DBB vs GT3540"

 

greg do u run a inovative t-66 ,does it spool faster and have more top-end than the GT35/40 or the t-78
HELL i read that you cn blow on them and they will
spin...

 

they shuld do a kit with the inovative t-66 dual bb
is it expensive to make a custom manifold for a t-66?

 

The GT66 is a larger turbo than the GT35/40 spooling will not be as good but the damn thing kicks ***. Imagine a Greddy T78 with DualBB and there is your GT66 with possilby a little more kick ***.

 

full boost @ what rpm

 

The manifolds are not expensive... its the turbo that costs and arm and a leg, which is why nobody is going to offer this in kit form. Nobody would buy it!

 

Yes, you can blow on the GT35/40 compressor wheel and it'll spin. You have to position the turbo so the the wheels are perpendicular to the ground.

If you do a search, you can find rpm and boost levels.
I saw about full boost around mid 3krpm's (boost controller turned off => 10psi). I believe I can hit 15psi before 3800rpm. My engine is a stock port engine (for now ). I also have a pretty inefficient manifold I hacked up. So I imagine the A-spec kits are spooling a bit faster than mine. Turbo response is incredible and the lag is minimal for a powerful single turbo.

Sounds alot like a straight GT40.

 

about how much power could the t-66
make @ about 18lb. boost with full
bridge port and vp racing fuel ,and
about how much faster does it spool up???

 

is it true if u port ur engine the turbo will spool faster.
can this be done with a t-66 ,if posible how much faster
would it spool up??? @ about what rpm

 

store sayz gt35/40 can rip up 2 700hp is it true?

 

a gt35/40 will woop a t-66 *** on the street.. but if you have a gt35/40 at the track and you race somebody with a t-66 running 25 psi with race gas ,be ready for them to hand you your back side and wait for you at the finish line!!!

 

the gt 35/40 seems to be a better chioce though..

 

**** no!

 

are you kidding me? A dual ball bearing GT66 will get **** on by a gt 3540? I know of non BB turbos that will crap on the gt3540

 

thats definately a better comparason

 

GT3540 is the RX6 on steriods...bout 450-475 rwhp MAX

 

thank you

 

but greg is the t66bb a good street turbo versus a gt35/40?

luigi

 

T66 is a fine steet turbo, especially in dbb. Ask Steve Kan if its a good street turbo

 

That's flywheel Hp on a piston engine. Not RWHP on a rotary.
