Buschur Racing tests the new HTA3076
We used the stock actuator on this dyno chart. We've since changed to the FP HD unit, but drop off in boost was pretty bad after 6000. Also, a very slight difference is that some of these figures had to be interpolated between known rpm/whp/wtq numbers. The most rpm area that had to be interpolated was about 200 rpm difference.
Wow very interesting to see the 3076hta vs 20G!! Thanks 9sec9!! Seems like until 5200rpms, the green owns, but then the 3076 starts pulling away....slowly. Looking at those numbers, I'd have to say you're not giving up very much by going with the 20G vs the hta3076. And considering the power differences between the 35 and 3076.....its starting to look like the 3076hta really doesnt split the difference much. Granted I know the OKIX car is totally full build...so is Dave's RS. IMO, after seeing these comparisons, I don't think I'll spend my money on the new HTA
I'm working on a green build for my car with the new manifold David will be testing and some other stuff. Will let you know as we go. I will talk to you via email we don't want to let the cat out of the bag just yet.
I really think these comparisons need to be looked at from the viewpoint that we were running 37 psi, not 31.5 . Turn the boost up on the 3076 hta and the power is going to go up dramatically. I think if both turbos were running the same boost, the hta3076 would win hands down. Maybe not in the lower-mid rpms, but certainly from 5000 up, which is what you want at the dragstrip. I really think the 3076 has a LOT of potential.
Wow you put more power at higher rpms than the hta3076 but are down in torque by over 150lb ft. How did that happen?
Also the gains seem bigger for the hta 3076 when put down in numbers versus a graph. Its a substantial improvement to 5000rpms. But the ultimate power the 35r can make is so appealing.

Theres a dyno graph from this site under (twin scroll 3076) by full race on only 22psi.
sorry having trouble trying to post image.
Can anyone elaborate why the power band starts so much sooner (max wtq by 4000rpm) than the graph posted ealier????

Thanks for posting that actually 9sec9 as your car is a great example of the Green and is what my dyno sheet would have looked like had I compared it, if I could find it. The Green is a monster down low and that's why it is my favorite turbo for a daily driver that is a BLAST to drive.
BTW, the Evo Green, it's a true twin-scroll turbo isn't it?
The twin-scroll thread you are looking at, is it evodan2004's thread?

I know you could make the normal rotation wheels no sweat, since you are milling the reverse ones out of billets anyway. But the divided turbine housing and a matching manifold - is that why you don't make one for DSM? Would take too much investment in manufacturing for the number of sales expected?
Hey wait - - whoa! You will probably make a normal rotation Evo Green anyway - for the X won't ya? You'd sell a jillion of them.

Yes it is evodans2004,s thread.
Ive seen evo greens make just as much power on pump same psi as that 30r twin scroll, and the dyno sheets are almost the exactly alike...so is a twin scroll realy worth it? well maby if it had an hta wheel. But an hta green is comming out soon that should be very intresting to see what kind of numbers that wil post.
