Buschur Racing tests the new HTA3076
The graph is a good comparison to see the difference between the 35R and 30R on his car with everything being controlled and the same. So you can see the differences between the two.
Still, as tested, it puts down way more power at 22 PSI, than I ever thought it could possibly achieve. The Black Bish surely has a mighty engine!
Would the 484 WHP be enough to propel the Black RS to to a 10.20 1/4?

wow, looks like this turbo would be best for people that plan on DD. cause at 22 psi, able to run pump gas, the turbo made 484hp, and 370tq... that is amazing. upping the boost to 30 only helped like 20hp, but 90tq... so i think this turbo would be best for the street.
looks very good to me.

all runs were with race gas if I'm not mistaken
I will try to answer all the questions, if I miss one just ask it again.
I am not doing any other testing on any other cars for the purpose of just testing. If someone buys one and we install/tune it then it will be done on another car.
My car was run on C16 on high boost and low boost.
The test on both turbos were done with identical headers, .82 turbine housings and 3" 02 housings. So the ONLY change was the turbo itself. That's why it took so long for me to test it, I want to test everything in the same housings with the same headers etc. I am waiting on the HTA37R which will be in this same housing too, that is the hold up on that one too.
The turbo reaches 20 psi at 4641 on my 2 liter, this is deceiving though as the HTA35r on my car also reaches 20 psi at 4931 rpm. BUT if we break this down further there is a big difference. For example:
HTA 3076 HTA35r
3,000 rpm 1.62 psi 1.21 psi
3,500 rpm 4.73 psi 3.54 psi
4,000 rpm 8.57 psi 6.19 psi
4,500 rpm 16.98 psi 11.98 psi
5,000 rpm 28.68 psi 21.63 psi
By looking at that you can see why there is better low/mid range.
