It looks like 4P cams, 1400cc injectors and an upgraded turbo are in my future! My car is quick now but I don't think another 100whp will hurt during competition.
We may eventually. Right now we aren't offering any work for the L15 because we have to change all of our tooling every time we machine a head or block, and it takes hours to setup each time we change it since the engines are so small....then hours to set it back up to go back to our normal work. We are at capacity with the work we have....so doesn't make sense to retool for a couple engines. The new machines, employees to run them, and shop space is a 7 figure investment to add it to our current workload.
8700 huh..I guess I may have gotten the last TR2 early morning online shopping.
Curious what this will do to my powerband. Built block, ported head, Ferrea off the shelf valve train, port injection, ID1700x, surge tank, Motec M142 Vit package. G30-770 ewg, 4 port mac solenoid. Current rev limit 8700. PPG 1-5 FK8 taller gear set, stock 4.11 final drive. Tuner: Daniel Butler.
your turbine is choking it, even on a stock cam...
Your turbine is the same size.. 35 psi and g30 isn't going to rev to 8700. My g30/ tr3 were falling off pretty good by 8300. The turbo was the restriction to rpm, not the tr3.. Pulling numbers out your ass

I’m not making any numbers up, nor am I claiming anything other than that 8700 rpm is what Daniel set the rev limit to.Your turbine is the same size.. 35 psi and g30 isn't going to rev to 8700. My g30/ tr3 were falling off pretty good by 8300. The turbo was the restriction to rpm, not the tr3.. Pulling numbers out your ass
Went from 608 to 725 (and 3 psi) on cams and CNC head so they work great together.. just be realistic here. I did 8700 with a g35 and made ~800 at ~8500.
Because why? You raised it to exactly what I said mine with tr3 cams, not stock cams and with a much larger turbo to actually make power at 8700. You also did it without any testing, which I already know the outcome (over spin and high exhaust pressure). You're killing the turbo and engine for no reason other than the perceived cool points just to say youre rev limit is 8700.
What turbo? Borg Warner 7173 EFR? Btw got my TR2 yestaday, will be getting installed and hopefully tuned this next week depending on DB’s schedule.Either way....just don't turn it that hard based on that graph. Fuel control looks erratic up top...or it has some boost control issue going on....or turbo is done for. Stock cams can't do it...the head and cam makes a big difference on rpm capability. Not all ported heads are equal. Put the cams in, tune it, and you'll be good to go.
I set my limit higher than I turn the engine. Beating up limiters is hard on engines...it oscillates springs and wears them out...and worse.
When I'm running my car hard I naturally feel the cars pull and if I go back and look at my logs....I'm shifting 8200-8300 whether I look at the lights on my dash or not. I have my hard cut up higher so I don't hit it. I've also set it up to try to maximize acceleration on 55-60 rolls (since I get flogged on 40 rolls) and I try to manage the power in 3rd where on a reasonable surface in 70 deg weather if I punch it the car naturally hangs at that 7800-8200 range as it tries to hook up....I allow slip % before it starts pinching the throttle, then the same in 4th which is more power to do similar. Its a balance to find the right power and traction when you are trying to roll race some 1000hp domestics on a good tire....they always get out a car or more while we wait on the turbo and if you have some traction its time to start reeling them in up top
Precision 6466. Its brutal on the highway. Responsive but can make more than the chassis can take.
