Dyno results PeakBoost 3076 Dyno4mance
Ok, I have revised my post above (#27), so it should be correct.
If anyone is wondering about the slight difference in the 3037 and 3076R's compressors, this is what I've found (http://cherrypicker.tripod.com/id6.html):
3037 - 49 LB/Min or 709cfm max flow @ 2.4PR @ 60% - 33psi max boost limited by compressor wheel speed.
3076R - 52 LB/Min or 752cfm max flow @ 2.7PR @ 68% efficiency - 36psi max boost limited by compressor wheel speed.
That tells us that the different compressor wheel trim gives the 3076R a bit more hp potential due to its slightly increased flow capacity and efficiency. This equates to an ultimate difference in power potential of maybe 30-40bhp.

Looks like a GT35 to me based on the graphs. I'm sure the owner knows what he has, but it looks similar to Ted's graph. It may be in fact the GT30/40 which uses the GT35R's larger compressor. This is the 82mm/64 trim compressor Ted spoke of. If it is, then more lag than normal would be expected.
Yes Zugu, a true GT3076 has the specs you listed.

Actually, what I've found (http://www.agpturbo.com/product.php?...275&bestseller) indicates the existence of that hybrid:
GT3082R - GT35R compressor with 60mm / 84 trim turbine used in 3071R, 3037, and 3076R. This is what is sometimes referred to as a GT3040.
However, the spool characteristics of a 3076R can be influenced by a good few different variables (including those HKS 280s), so I wouldn't think someone would be selling a 3082R as a 3076R

If that's correct, the only difference between a 3037 and a 3076R is as follows:
3037 - 76mm / 52 trim compressor
3076R - 76mm / 56 trim compressor
Confusing innit?

The GT3076 is the only turbo that comes in such a variety of different inducer sizes.
I wiil find out about the turbo that I have. it does have a .82 I will find out more again this was on 110 race gas. on the graph the car looks to spool late but on the road it is another think.

Ok, I have a headache now . . .
Anymore info on this Autronic PNP ecu? How much? Where to buy? Any tuners in Cali? How do you like the unit? How does it compare to a AEM Ems? Is it easier to tune? Great numbers!!! Especially on a DD!!! Wow

Hi guys!
For more information on the Autronic and dealers in your area you can visit the website.
http://www.autronic.com/
It is a very good system; As is AEM. I have tuned many of both. So it comes down to what features you want and how much money you would like to spend. The AEM takes a little longer to get through the base fuel map, as it uses a pulse width table. And the Autronic uses a true VE table for the base fueling. Both systems are easy to tune as the same basic methods of tuning apply to both.
And I travel!
thanks guys

To all of those who see the graph and thinks it supper laggy your are incorrect it is maybe 800 to 1000rpm slower then the stock turbo on the road. I have ridden in the car and watched the boost gauge and everything. Also this car is a complete rocket, I almost creamed my pants it was so awesome. It really makes we want to get bigger turbo now. All I can say it's a MONSTER and I would hate to be the guy that pulls up beside Todd, becuase all thats gonna happen is to be humiliated.
If the car owner or dyno shop can post the boost chart, then that will really help. As it stands the turbo looks laggy and there is a lot of power scarificed at the mid range from a stock set-up.

Sorry friend I am not the owner of the shop, but I try keep a record of every car that I tune for my customers. With Todd's permission I will post this graph for him.
This is what is called shootout mode on a Dyno Dynamics it gives a very close representation of actual flywheel output. If you will take note it is only one run after the normal WOT pull with measured at the wheels power represented. But this will show you the actual boost level used.

As for the autronic I think it is a better ems, if you look at autronic they have been around a lot longer then aem. so that is why I went with autronic. far as a tuner I think Chris did a great job, and he will travel if you need him too.
