11.0:1 Compression with 93 octane?
Can you run a 11.0:1 compression with 93 octane? Whats the highest compression you can run with 93 octane?
Thanks,
Spiro

spiroh,
That's a very general question. Are you planning on running i.e. Motec, DFI, PMS, or any computer management system for fuel and timing? If not you will denotating your engine and in some instances you may not even hear it happening. Give me more info on what your trying to do so I'll can help you.
My mustang runs 10.0:1 compression with 14 lbs. of boost on 92 octane gas and doesn't ping, but I have a Speed Pro computer management system to control everything during a race.

I was thinking of doing the 3.5L upgrade and using high compression pistons. If I dont do the 3.5l upgrade I still want to get custom pistons, and use a higher compression to gain more HP. I had no plans on purchasing any fuel management tools. I do have a V-AFC, if that might help.

CL Power,
That's because a fuel map curve developed by acura has been burned into the chip to accomadate the high compression. Just like the CL type S's. They run I believe 10.5:1 compression and don't ping either. It's all depends on computer management.
For example Scott,
You and I know if we were to put together a V8 motor together with 11.0:1 compression and 93 octane and run it with a carb with no computer it would ping during everyday traffic. Period. Spiroh ask a question that was to general and not specific. I would hate for him to think it's okay to run that high a compression on premium gas without the proper fuel management system.

CL Power,
Who said I was bragging? I was merely giving a example of computer management. By the way, my Ford mustang runs high tens in the Qtr mile and I'm the slowest in my mustang club.

Spiroh,
Depends on the application and vehicle. They can range from $800.00 to $3,000 dollars. They are not cheap, but it beats blowing an engine and saves you from burning a new chip for every new modification added to you car.

If you are worried about detonation get a J&S safeguard unit. I had one on my ITR hybrid and it worked great. They are about $500, and it only retards the timing on the cyclinder that is detonating. So you can run higher timing than normal, and it will adjust itself. It also comes with an A/F montior. Endyn (http://www.theoldone.com/) loves to use it on his cars, so you know it has to work. Here is some old info on it that is from the hybrid board. http://hybrid.honda-perf.org/forum/a...ls/jsinfo.html

Thats some sweet stuff. I wonder if it would work on the Type S. I read were it said that the Honda/Acura has only changed the wiring once. But who knows in our case.

I believe this thing ranges in the 1-1.5k range...

I have an 8meg movie of when I took the ITR swap to the track and you can kind of see how I mounted the J&S montior in the dash. I did really shitty that run, I think it was a 14 something, but I weighed 200 and my brother weighs 220lbs plus 17" rims. And don't laugh about the shitty camera work. We had to sneak the camera in with us. And notice the 9000 rpm shifts. Man I miss that car sometimes. http://groups.yahoo.com/group/Honda_....../Happy2.mov
