I was just curious how you measured because most people don't;-) Sounds like you did the calcs thoroughly.
Could you tell at which RPM it started to hit? Any idea what the static piston to head...
Charlie:
Point well taken.
Did you mill the head as well? Or is 13.8:1 the resulting compression with the wisecos(as measured)? Just out of curiosity, how did you measure this?
Remember slight piston to head contact is actually desired for optimum dynamic squish. http://www.mototuneusa.com/the_factory_superbike.htm
I doubt that slight(I do mean slight)contact is causing...
I posted about cal poly a week or two ago. They ran some sort of (real)electric supercharger powered by a dedicated GM alternator(100A) driven with a belt on the crank shaft in 2000. So yes it...
Cal Poly(I think), ran an electric supercharger powered by a dedicated GM alternator(100amp?) in 2000 I think. I think they placed top three. They must have made good power becasue they had to push...
Yea, a little more info would be good. Are you getting ref/sync errors? What kind of coil driver are you using?
I am sure some of the current UW guys might chime in, as it has been a couple of years since doing much with MoTeC. From my 3 years experience with MoTeC hardware and customer support I could not...

Kind of pricy, but Aircraftspruce has come through for me many times!
If you want to harden it you have to do it after welding!
As far as I know it should be tied to ground. Make sure your positive and ground wires are plenty big as well, at least 10ga.
Doesn't sound like it can be fixed for $100, the chain isn't the problem, it is the old "I need the chain 1/2" shorter but can only take out an inch" dillemma. You can only take out full links not...
Many F2 and F3 parts are exchangable, internal and external, don't ask me how I know. Something about a frankenstine motor in an old car.
To back up Denny, since I was there during the 2001 F2/F3 mayhem at comp, yes they are directly compatible except for the shifting order. You have to swap your shift cable from top to bottom or...
Remember, that you only have so much *usable* fuel in the tank i.e. fuel starts sloshing, foaming, etc when you get towards the bottom of the tank. So you definetly need more than 5.72L in order to...
Hey Denny, are those pictures big enough? They won't even fit on my 21" monitor!

Wiseco makes pistons for most sportbikes motors. For F4/F4i I think they claim 12.7:1 compression over the stock 12:1. About $500 per set?

Conisdering that most 600cc sport bikes make more that 100RWHP (maybe 115-120 at the output shaft?), and the record FSAE car is like 84 RWHP (100 at the output shaft? more losses in a FSAE car I am...
I know that in previous years our team has shaved F2 heads all the way to the valve seats without detonation problems, even while running 92 octane pump gas during testing (stock pistons). But as I...
Sure you can do it with a MoTeC, just set your fuel table values to 0 at some load and RPM sites. Say above 7000rpm and, 10% throttle and under. Haven't tried it but I am sure it would do the same...
At the University of Washington we have been running the MoTeC M4 Pro for three years and I have been involved with tuning from the beginning. We are very happy with its performance. The only...
We tried it in 2001 and it seemed to be alright, I think the motor ran cooler with the air-oil cooler, since the heat from the oil was being dissapated to the air instead of to the coolant. However...
Yea, I am pretty sure he is talking about the Chinook helicopter built by Boeing. As far as I know it has a couple of 1,000HP+ turbines in it. I think unlimited hydroplanes use them for power. ...
Same story with our land and sea dyno. Always 10-20 HP less than on a full size car dyno. I think the water pressure in our building is probably inadequate and fluctuates day to day.

I second the suggestion of being way too rich and the engine misfiring due to that. The O2 sensors will spike lean as soon as it sees a misfire and all that free oxygen flows down the pipe. The...
