My current 62.9mm Xona Rotor is definitely better than the similar but older 3586HTA, having run 7.58 on that thing in a t3 housing. To compare non nitrous ETs on both turbos my best on the 3586 was a 8.3x and on the XR version 7.93. Not a good back to back test by any means, but the XR turbo is...
Yeah, it looks like you guys are right. I could have sworn I remember looking it up and the standard 35r turbine being 64mm, but it indeed 62mm. The HD3582s are 62mm as well. I definitely swapped turbine housings between the 3586hta and the HD3582 BB and JB, but I did use the XR turbine housing...
It's basically a 7864S, just stretched 1 more mm to the maximum 62.9mm allowed by most rules. Worth 2 more lbs/min. The 3586 used the standard 64mm GT35R turbine. It's also the same size turbine in the HD3582 series turbos. Turbine housings interchanged on all of these for me. There may be...
I'm not sure if this helps, but testing a XR 8064S vs 3586HTA, I have some data. Same size turbine wheel, in fact I installed both turbos in the same ~.82 T3 housing. Back pressure dropped from 1.4:1 to 1.2:1. There is a perceptible increase in lag on the 2 step but nothing that matters to me...
After running 8.39 on a Forced Performance HD3582 (their low budget 35R variant) at the shootout last year, I decided to try some other turbos in this size range. Over the winter I switched to an older FP 3586HTA that I borrowed from a friend. That went 5.12 and 7.99 for ET with a 100 shot in...
I'd like to touch on the AFR wave issue quickly, since it has become a major problem for a lot of people in the last few years and people are probably finding this thread searching it. It's unrelated to global scaling. Global scaling, by definition, would move all the peaks and valleys up or...
I did indeed run 7.92 or so at 180 MPH back in 2014 on a T3 Super 99. 2500 lbs or so, so the car is light but not crazy light. Our street class 2g was 2750 for comparison. I give more of the credit to the turbo, it was a solid unit. Back pressure to boost pressure was in the 1.4:1 range at full...
I think I've missed some updates here. Sometime over the winter I reset the no nitrous record to 9.92 at 126. It has gone 137 I think for a best MPH, I don't remember why I lifted there. 60 foot was a 1.33, which blows my mind a bit (this was still no prep in the winter).I then put a new...
Thanks guys! That was a fun side project for many years. I've always said that when I put the 16g on the car for shits and grins back in 2011, and got it down to 10.31, that was what made the car fast. I was stuck for years at 8.80-8.90, and after that, marched right on down to 7.90. Being...
