i don't understand what happened to this thread adn i dno't wanna read all this bull**** either but i can't understand this statement. if there is no difference between the 3071 and the 3076 in spool (per vishnu's opinion) nad there's no difference between the 3076 and hte gt35r then why don't we all just get big turbos? this makes no sense to me unless there is a distinction between the 3076 and the 3076R here.......

jj008, to me a 700 rpm difference in full boost isn't worth the difference between being able to make 500 hp and 600+ hp. I'll take the 700 rpm's and the extra 100+ hp anyday.

and in reference to this sentence above... you would... but i wouldn't :\

the ams kit makes 420 and that's on a dynojet which reads high but it what everyone is used to. the 3076 will make a bit over 500 on racegas. there's no difference in power production between the 37 and 37r, you just get a different power ramping.

Thanks for the Info

Hey David, I found this thread because I have been hearing about your cast stock-looking manifold in your turbo kits.

Is there any new developments in this kit?

I noticed in this dyno chart that the torque number seems really really low for such a large turbo, even on pump gas. Is there a reason for that?

Why not look at the BB GT30 Kit, that would be your best bet and david has one for VERY cheap

There are no "new" developments in the kit. We have changed turbine housings to one that matches our manifold design. This new turbine housing has an integrated wastegate port. We use a 44 mm Tial wastegate on all the systems now. This new turbine housing is very lightweight and stainless steel. Every turbo kit also has the manifold ceramic coated too.

The GT3071 on our dyno with 93 octane/alky made 350 whp, that is a good number on our dyno for "small" turbo. That is the car I was speaking of earlier in this thread. Our GT35R kit has made (as of Friday last week) 551 whp on race gas on our dyno.

The black car is still getting a cage put in it, when it comes back I hope to be able to post some new results.

As far as reading all the "bull****" tynidex, I don't know what to tell you. What I type is what I think.

Thanks Dave, that dyno of yours is a real heart breaker.

brining an old thread back to life...any new developments/impressions dave?

I am going to have to agree with David, we tuned my personal car this weekend with a 30r .63 and made 360whp on 91, 453 on race gas. Pump was 21 psi, race gas was 26. The turbo was out of breath, we upped the boost 1psi to see what we would get and gained .5whp so she was done. The car has a pretty heafty powerband, but still doesnt fully come on till about 4k. I think a .63 35r would have come on only a fraction later and made much better numbers. I am pretty happy with the numbers the car made however with that turbo.

I ran a 11.54 @ 121.6 this weekend on pump gas, 26psi and alky with BR's OLD STYLE GT30R (aka BR500bb). The tubo makes some pretty good low end power though, I was hitting pretty consistant 95 mph 1/8 times. Interesting thing is upping the boost to 28psi, adding some race gas, and leaning her out a bit (timing looked good and egr's were 850c) and it diden't go any faster. This is the OLD kit from BR with the integrated wg on it. I am pretty sure if I hammered the shifts, leaned it out a few .10 and pulled the usual low 1.60's it would run a solid 11.40 and possibly a 11.30. I think that is about all I am going to get out of this turbo.

Nice times 4ring. The car could be tuned a lot more aggressively on race gas and run even faster. Just making the point, the times you are running now are great!

I think your right! I am starting to think with some 280's, more timing, and the new turbine housing she could go 10.90's. This run was made on 264's.
