what is the c tune? I didn't see it on his site.

Tom M'Guinn

What meth injection kit/parts are you using? I've been thinking about trying that or E85.

The C-tune isn't an advertised kit. Its for the very few people that are in a situation the M-tune won't cover.

99.9% of 951s should use the M-tune.

I cannot speak for him but for a build of your caliber it is Aquamist or bust. HFS3 or 5, yes, spendy but worth every penny. The boost failsafe alone is a tremendous safety net. You can run50/50, 75/25 or 100% meth on pump. No need for a bigger IC either, IAT will stay consistant, essentialy no heatsoak with no timing correction problems or knock/pre detonation.

However E85 will yield significant more gain.

Personally i wouldn't go meth. straight to E85... just because you don't have to worry about filling 2 tanks and when the meth tank runs out on a track well that's slower laptimes.

One gallon last approx 25 min under track condtions. You can fit the pump and a 5 gallon container where the spare sits, you are running out of tire way before you run out of meth.

I personally still prefer e85. I DD my car and it runs like a factory new car without any additional worries about filling tanks at all. Honestly for me I couldn't see doing anything else.

Thanks for the input -- I don't think I have enough fuel flow right now for e85 at full tilt with my single 044 pump and 83lb injectors. May have to get working on that. Sorry to take this off topic. Rock on Todd!

I prefer E85 too but availability but it is not available in many areas.

E85 is the best thing since sliced bread for high performance but still very limited in locations. So that leaves meth injection or paying $10-15 per gallon of 110 octane, etc.

Tom, maybe some chats on pm with Blown 944 or Rogue and they might inform you that you do have the flow support for e85.

Josh: I got your new marketing slogan but you have to promise me the first shirt.

Rogue Tuning - "Go Rogue!"

Which fits the 951 community to a T!! LOL

I didn't know sliced bread was used for high performance.

Need a better view of the speedo and rev counter dammit. Glad to see you are enjoying your car btw.

Any 1/4 mile times for your car after the C tune ?

toddk911

I developed some scoring last winter due to grossly rich cold starts which cause some wash down so I will be doing a re build this fall/winter. Therefore, any dyno or 1/4 runs with C-Tune will have to wait till then.

I just need to decide how bad *** I want to take the rebuild. lol

I know I will stay 2.5 but am thinking about some head upgrades; springs, lifters, etc. Of course I have to see how Josh feels about a 7,500 redline with the meth inj and 25psi.

What is the highest recorded top speed on a 951 2.5????? lol

toddk911

Well, if it is wheat bread yea, since you can make ethanal from wheat. lol

Although, I'm thinking the exhaust would smell much better if running E85 made from barely and hops!
