it's always an absolute pleasure to read threads like this. so often, I read threads that have great plans, great execution and great details and something happens that keeps you from seeing the car actually work. you've had it built and you've had it built WELL!
this almost sounds like surprise, but I can't see why. the very fact that you (and the other people involved) are not so shortsighted and greedy to try to max everything out speaks volumes toward knowing what it takes to build a strong, RELIABLE rotary. props due!

If I may be so bold as to ask (I mean no offense and you're almost certainly a better race driver than I am): Why didn't you go faster than about 40 or so through the sharper turns? I feel like with all the room and power you had you probably could have gone faster. Very nice car :thumb:
Next time out I will be on new rubber and hopefully better times.
The day before this video, I was running 1:56 times out there... tires were really bad during this video!!!

Ha Ha... even my wife says it looks like I was babying it around the corners!!! Actually I was on tires that were two seasons old and should have been retired long ago.... I figured I had about 716 track miles on these tires.... A LOT!!

I also want to add water injection. I could tell that I was experiencing heat soak in the intercooler.... not too bad...but it was there.
Water injection will be one of my future projects. I will do a write up when I do this!!

10 PSI boost in one engine does not automatically equate HP the same as 10 psi boost in another engine.
Case in point:
1st, My engine has a modified BNR turbo with a Garrett TO4 Housing, clipped turbine wheels and fully ported. This change alone will make more HP at the same boost than a stock turbo at 10 PSI.
2nd, I am running a Haltech stand alone fuel management that has been 100% spot on tuned via dyno by RRR in Santa Ana.
3rd, this car has a very efficient exhaust system, custom air inlet, wastgate management that allows boost to come on and stay at set amount. All allows engine to make more HP at a given boost.
4th, on a dyno I have the luxury of cooling the intercooler with water mist before each run to optimise charge air cooling for maximum air density.
Lastly, I run racing fuel which allows tuning with a radical timing curve that one could not even get away with running pump gas.
So, keep in mind... your results may vary!!

EXACTLY right!!! I wanted reliabilty. We actually were at higher HP levels on the dyno, but backed down the boost due to injector duty cycles getting too high. The only way to make more power with this combination is with larger injectors.
I also want to add water injection. I could tell that I was experiencing heat soak in the intercooler.... not too bad...but it was there.

I'm wondering where the heck to mount the pump.
Couple Q's about your swap:
- How did you plumb the water pump neck to the radiator -- is that just a silicone hose?
- Are you running 3" all the way from the downpipe? I'm taking my car to get fitted soon and I didn't know what to expect in terms of what actually fits.
- Any pics of the swirl pot setup? I've got the actual tank but I'm wondering how you mounted the lift pump.

Maybe you are in the same power range at 10 PSI boost.... maybe not.

Nice build. I noticed your shifting at a low rpm for a rotary engine. Sounds like less than 7k rpm. You should be able to bring it up to at least 8500-9000 rpm and that way you could get more top speed in the straights and all around the track.

He said he was running out of "legs" on the top end.
