I just realized that I never posted this. The first run is at 1.4 BAR peak, 672 rwhp. The second run hit 699, same fuel, 1.5 BAR peak (no one let the camera-guy know they were doing another run).

Anyway, next week I'm filling the tank up with straight 100 octane and will start datalogging again. After that, I'll start turning the boost up some more.

Since I've had the car back, I've been running 1.4 to 1.5 BAR on straight 93 octane as well as 94.75 octane (a mix of 4 gals 100 and 12 gals 93). I'm very curious to see how she does on pure race fuel.

Awesome power on pumpgas !!

BTW.....Do u think TPC dyno read low???

 

I don't think so. Why do you ask?

 

 

Is the fuel quality and octane consistent doing it that way ( mixing )?

 

excellent power on pump gas. It was hard to see the afr's but they looked good as well from what I could tell

 

Well, it's a definite improvement over straight 93.

I'm actually running the exact same boost that I run on straight 93, but I added the 100 to see if I can spot any differences in timing while datalogging (I haven't yet). I'm not actually going to increase the boost until after I get straight 100 in the tank. Then I'll go to 1.6 BAR, and then maybe even 1.7 BAR depending on what the datalogs say. I won't go any higher than that until I get 104+ in the tank.

See, I have 2 maps in my tune; one for 93 with very low timing, and then one for 100 and up for higher boost that adds timing, so I should see a definite bump in power.

 

According to my datalogs, the Lambdas (AFRs) have been perfect so far. No hint of knock and no pulled timing. Both Mike and Todd are very happy with this tune.

 

I did not keep up with your mods on this one, I have to back and look in your other thread. that is excellent power on pump

 

700whp on pump. WOWOW that's a little bit rediculous

 

700 whp on pump.....that's damn near 200 rwhp per liter...PURE!

 

Thanks, bro. That was actually the goal. Many high powered cars on here only make big power on pure race fuel, which gets expensive and can be a huge PITA.

I wanted this car to be able to make 'good' power on 93 and 100 (since both are easily accessible near my house) and then be able to make typical race gas power with higher octane and more boost.

The one thing I really loved (and missed) about my SC'd Z06 is that it made 700+ rwhp on the street, all the time, on 93 octane. When I got my GT2, it was tuned to run 93 to no more than .9 BAR, and it needed 104 octane or higher to run 1.5 BAR! It was very frustrating...hence, my reason for the new setup.

I also wanted to stay away from meth/water injection since I'm still paranoid (rightly or wrongly about relying on it to keep things safe.

 

thats very great bob ...

great work

can you please tell me how you switch between the 2 maps

thanks

 

TPC dyno'ed 997 GT2 and it made VERY low numbers

I know 997 GT2 480-500rwhp

 

I turn up the boost using an EBC. The ECU switches maps all by itself.

Who's Bob?
