Not a bad idea...one of the models has a built-in infrared temp laser...good excuse for me to get it as I can use it at work...lol http://www.biondoracing.com/DataRecorders.shtml scroll halfway down the page
Heck yeah, it would be awesome to have a wideband O2 AND an EGT probe. Then tie it all into a datalogger and you would be set up! Thats my plan if I ever get the turbo on my car......or even get the car back on its feet for that matter AC
Don't Understand I don't understand the skepticism of getting 350-360 H.P. out of a 302. My motor is a stock bore 302 with trickflow twisted wedge heads edelbrock rpm air-gap intake with 9.7 to 1 compression. It has a very mild hydralic roller cam .533/.544 lift and 215 duration with 1.7 roller rockers and a 650 double pumper to top it off. And it is making 370 H.P. and 350 ft. lbs. of torque at 6300 rpm's at the fly wheel. I have the dyno sheets to back this up for the non beilevers. If you need to see them.:confused:
I agree. 350 HP from a 302=easy. CarCraft made 400 if memory serves me correctly....with AFR165's and a MILD short block.
courier, couldnt a bad plug/plug wire throw off a tune? even if so, it shouldnt take 8 o2 sensors to figure out such a simple problem.i really dont know where i was going with that point. sry : /
I think CarCraft has the magic dyno or something. AFR or not, those are some almost unbelievable numbers. I have NEVER seen any dyno sheets besides theirs to back this up. That would be what...about 320RWHP minimum through a T5? Havent seen it with 165's. I would be more inclined to believe twisted wedge heads made that kind of power as they flow better than the AFRs. This is NOT to say that 400HP cant be made with a 302, just that with AFR 165s it would surprise me. AC
maybe its just a magic motor...i hope i have one question - does more flow ALWAYS = more horsepower?? or do properly matched heads for the motor make more hp, e.g. depending on compression ratio, cam, etc, etc...could the afr's perhaps just be a good match for what carcraft was runnign? i dotn knwo what to believe because there are so many different versions of the "truth" out there...can anyone help me out? -beau
I don't know what they did. Maybe magic, maybe just luck (and I wish they'd give me some of it too!). I do know that flow numbers are important, but not exactly a apples-to-apples comparison of different heads. For instance take a set of Yates big-port heads and put 'em on a 302. Ports are so large that it'd take a half metric ton of of epoxy to get enough velocity to actually get all that air into the cylinders at anything lower than 12,000 RPM. From what I understand, that's how AFR heads make their power. From velocity. Velocity=torque and torque=HP no matter what engine it is. Mis match a set of 165's though on a race-built 427 stroker windsor and you'll be rewarded with a awesome low end but falls off above 5500 RPM. It's all about careful selection of parts. I'm in that predicament now. Whether or not to go with the cam that was recommended....when the one I have now worked great on the combo I DID run.
Good point on the proper matching of components. Its true that too much head or the wrong cam on a small cube engine can adversely effect HP. My main point was that I have seen a few AFR headed combos and NONE of them come close to the 400HP mark(at least N/A). Sure would be nice if Im wrong though. Any easy 400HP is a good thing AC
my comment on this isn't really worth anything. Have just been having a blast reading this thread and thought I'd resurrect it. Makes all my repairs seem minor. Respect!
Yeah I dont think anyone has touched this thread for a while. but i was gonna add that AirFlowResearch has dyno charts on their website for N/A 302 and they make some goood power. I bout a pair myself havent run em yet but hope to be pleased.
MY AFR 165 Competition sieres head gained me 10mph and a full second over a 58cc early ford casting head. As of a few months back it is making a touch over 400 at the crank at 7150 rpms. With stock 302 bottom end, 10:1 TRW flat tops, 520/540 224/244 @ .050 hyd cam, RPM Air Gap and 750 dbl pumper.
