all turbos take time to spool, your car probably pulls through 1st so quick that the turbo never has time to fully spool. i have a larger turbo than you but just as an example i cant get past 5-6psi (Boost set at 8psi) unless i eat the rev-limiter for a second which i never like doing.

 

i love lag on a street tire car.

You dont wanna hit full boost (more than 5) on street tires anyways if you ask me

 

let me be the 1st to tell you to get rid of that junk LS head, get rid of the cat, and put a 3inch on it, then report back with your new found power.

 

1st gear has the least load on your motor as well due to highest gear ratio, but its probably because you are just ripping the gear in a split second

I agree, i have a similar setup to yours using a T3/T4 57trim .48a/r and by the time i hit 8psi my tires are loose anyways.

 

i think u not hitting full boost in 1st means the turbo is properly sized, not too big


does the car not burn out in 1st, im willing to bet it does even at said 5 psi, so whats full boost going to do other than spin the tires even faster?

 

It's normal not to make a lot of boost in 1st.

 

i hit full boost in 1st and don't spin but then again my street set up includes traction bars, quafe LSD, and BFg's

no wheel spin in 1st just a little spin in 2nd and chirps 3rd
im not asking for my wheels spin but it just feels like the power is not there maybe i just need a new tuner.

i had the same exact turbo on my other LS as well that i sold and 1st and 2nd gear will rip and spin like crazy the set up i have now is similar just a diffrent turbo and high flow cat installed and the response is no where near the 57 trim, also does anyone know what trim this turbo is by the measurments?

Exactly... I don't spin on warm tires either with my GT2871R.. 12 psi in 1st gear in summer mode and all my car does is eat STi's from a 1st gear roll.

I just hate it when guys says lag in 1st gear is good for traction. Lag is good for guys with shitty tires and suspension and like to accelerate like a Civic DX for the first 2-3 secs. Any stock G35's, 350z's, or anything with torque will rape you when your car lags at 4-5 psi after 5000RPM in a torqueless Honda.

This just in... Roll racing is Gay

This is No lagging when you launch off rev limiter

not true. there wont be if you have a 2 step or whatnot. but when my brotherhas launched at rev limiter, he was actually in vacume without a 2step or launch control.

so it bogged for 2-3 sec and there was no boost...and this was off of rev limiter?

all the way to 8700rpm. it bogged about that long yes. this maybe just a special case of no boost at rev limit, but ive only had that one experiance, so it may be different with other cars.

If there is no load then there is no boost, aka 0psi but once a load come on and It still bogs @8700 rpm I might look into a new tuner

me and my brother already established that. we were gong through the maps on his e-crapage and realized just how rich the thing was running. can't remember the AFR but it was pretty damn rich. and before we did anything to the tune, the rev limit was set to 8k and he has a stock ITR motor, they rev to 85xx stock. so we raised to 8700. and tuned accordingly.

wont go to intec to tune again

I love building boost of the line with my 2 step,and actually having the suspension to use it

 

im not sure but i thought that u need a specific manifold for twin scroll housing turbos

why are you useing that greddy program? OBD2?

46 trim... how come the measurements don't match up this thing has a huge exducer compare to the other t04e wheels see link below could it be the super 46 trim which only shows a compressor map.
My 46 trim measurements inducer= 55.55mm exducer= 81.80mm
Garretts 46 trim measurements inducer=50.88 exducer= 74.93mm

Here the same... I don't hit full boost 'til 5000~ish RPM and don't hit boost at all in first gear. I love the lag..
