Just wondering how many people are running there single turbo kits, and what kind of numbers they pull out of them at what psi. and how they compare to the hks to4r.

im still not sure i want to go single but I dont think the twin setup will do it for me and there isnt enough info on the bnr twins. Im looking for lots of power my goal is 400hp min. and i will not go Greaddy I have heard too many bad things about them!
any suggestions? or coments on a kit?

 

Find Wargasm's dyno comparison site. However, be aware that lots of other setup items (other components, tuning, dyno calibration) can affect the results. And also boost may vary from the stated level, both because it can be tricky to get the boost control to hold a solid level and be consistent.

I haven't done it with my own dyno testing, but it would be great if dyno charts showed boost and A/F ratio versus RPM and that it was easy, common, and trustworthy (calibration, consistency in measurement) to do so. That would make it easier to do comparisons like this. Unfortunately, it doesn't appear to be easy or common and I have some doubts about consistency (for the sake of comparing one graph to another) if we did have this info on all the graphs.

You will find that there are a lot of turbos out there that can make 400+ ... The question is at what boost? What AFR? What timing numbers? You should decide what your realistic goal is and your boost level. Are you talking pump gas or race gas?

For example, when I bought my turbo, my goal was 400 @ 15 PSI. I actually got 405 at 14 PSI, which is pretty good planning

Pick a HP level and a boost level and you're halfway towards making a selection

 

Give me a few weeks, and i will give you some numbers on the Gr67 kit. In the mean time: http://www.gothamracing.com/pics/Ste...rbo%20kit1.jpg

All i know about these runs is that they were done on a mix of pump/race gas, and I believe that the fuel pump was almost maxed out. There is a thread on here somewhere, but I just couldnt find it...sorry.

 

sorry... found it : https://www.rx7club.com/showthread.p...9&page=2&pp=15

 

how does it compare to the hks to4r kit over all?
