313whp GT35R
 

I had Scott at Mazsport dynojet the car today. This is Manuel's (RX8PR) GT35R kit that he sold to fund his 3-rotor project. It's running Mazsport's upgraded fuel injectors and pump, Bosch HEC 715 coil packs, and the Interceptor. The gutted cat, stock exhaust, and makeshift intake held us back from making really big power. We must have made 20 pulls and called it a day once we went over 300whp. The last picture is from the night I installed the kit and things aren't so messy anymore.

On a side note, I was really impressed how Mazsport's fan mod kept temperatures at bay.

NIce numbers, I like the torque curve!

How much boost are you running?

10 pounds. Manuel hit 327 @ 11.5# with a 3" exhaust, so I think we're on track.

nice! what kind of fuel were you rumming? what were the afr's at? how much timming? how many lbs of boost?

curve looks good, but ive noticed that all turbo renesis dynos put out about the same amount of torque. what will it take to see 280+ ft/lbs of torque our af a turboed renesis?

Running 93 octane and I'm pretty sure all the boosted AFRs were in the low 11s. Timing is still pretty conservative, but I'd have to log onto the car to give you some real numbers.

Nice numbers....I like the oil catch can :D:

LoL is that what I think it is?

^^^Yes. We were out of Guiness. Seriously, though; that's just one of the many small things that have been cleaned up. I now have a proper oil catch can.

Does anyone have any time slips after having this turbo installed or has it not been long enough yet?

I'd like everyone to know that the turbo he is running isn't even hitting it's efficiency zone yet. It's got tons left in it if they decide to really turn it up. Can the engine handle it is a different questions altogether.

I noticed you had no strut bar, is that because it won't fit or did you take it off just for the install?

The strut bar was removed only during installation. It fits fine!

RG: you're right. Right now the intake is sucking in air directly from the radiator. Assuming that the intake air is around 185*, it looks like I'll exceed the efficiency graph at 10# if I can lower the charge temp a few degrees. The turbo should really start to take off at 14-15#. We installed 2mm apex seals since Scott says they'll be stronger but I'm still a little gun shy.


I should give a big "thanks!" out to Manuel. He did a great job supporting me and working though our language barriers.

Why is the MAF sensor connected ?Doesnt the Microtech run the Air fuel and ignition directly?
air intake temps perhaps?

^^^I don't have a good reason for that. The car will run without it, but it starts to behave stangely. I asked Mazsport the same thing and the simple answer is just keep it there. I think the computer still uses it for temperature and may even have something to do with the throttle body.

as rotarygod say's he can get a lot more from this GT35R.....................
but take it step by step.

I'm glad that you had installed the kit on your car!

next step, 3" pipe?

Manuel

i'm willing to bet the engine can handle it just fine...it's the octane that's in question. piss some alky in there and see what's up.

3" pipe is definitely in the cards. Scott and I talked about methanol but if I went that route I'd probably engage it like nitrous: a switch that engages the methanol system and a methanol map. Of course, I still have a nitrous kit lying around from the Miata.

i think he is right... engine should be good for about 400 but tunning and the bad gas might kill it before gettign there...

i am interested in this also... torque is what gets you moving ... i think... also how terrible is gas mileage on turboed 8's?

or how about you run your 8-10 psi daily, and set the meth to turn on at say 11 or 12 psi... then you don't have to fuck around with extra maps and switches.

During normal driving, his fuel economy should be just about where it was before the turbo. When he gets into boost, however, to have some fun - all bets are off. :)

Because if I'm out of Meth then I don't want to accidently boost that high.

Are you still talking about CARS?? :D

You just run a boost controller. Low boost levels never get you into the Methanol injection range but high boost does. You have a sensor on the methanol tank telling you level. It's like a fuel tank. You just listen to what the gauge tells you. It takes a while to go through it anyways as you'd only be at full power at higher boost levels before it started to kick in. Once the low level warning comes on, run only low boost. The only way it can do harm is if you ignore it.

^^^That's exactly the chance I don't want to take. What if my wife is driving the car? I need to make this car as fool-proof as possible.

I found your 500hp methanol thread super-interesting, but there are many more projects I need to complete before I do something like that.
