that gives you a .3705 factor according to Bret's algorithm, which is not that bad at all. that algorithm is as good as any. would i want to run 24 heurs du mans with that combination ?
maybe not. would i go drag racing with it ? oh yeah buddy.

Re: 1.88 Honda rod journal ???s
Bret,
it has taken years but i finally think i fully understand the balances of journal overlap in conjunction with bearing speed.
thank you.

Re: Quarter jr Bundle Offer !!! (Update 3)
Good deal. This could be very helpful for a lot of folks. Question: If this goes far enough for Clutch Pro, would it be possible to switch out for Clutch Pro M ? Also, I'm assuming Clutch Pro will let you substitute the result of the gear multiplications for 2nd, 3rd, and 4th to calculate slip rpm i...

I did ask in a previous thread about bearing crush with no answers. Should you be looking for more compared to an iron block. Will the expansion of the bore decrease the crush? how much should you have with the alloy block? Mitch, Here's what I found, and keep in mind these afr are an old set of be...

so whats the consensus? do you run a little more main clearance due to block distortion from heat. something like 3-3 1/2 thousanths. this will be a fairly mild engine as far as racing goes. maybe 850 hp. i need to buy a block.what do you recommend? Based on everything I've read here and my own exp...

We run the same clearances as we did in the bowtie block. The only thing we did different was the deck clearance. We run the sleeve .005 above the deck on the aluminum block. Same .005 we use in the Fuel Car with the billet TFX block. LOL. You're making me skeerd ! Well, if I try it, I'll do it to ...

Yes, to paraphrase jimivice , a hole (e.g. a main bearing bore) in any material that exhibits thermal expansion (i.e. pretty well anything) will get larger as it's temperature increases. Since aluminum expands at about twice the rate of iron, the bores will grow larger than for an iron block. Given...

On an iron motor we ran tighter clearance and with the same oil clearance on an aluminum motor with same crank clearance I spun 2 main bearings. I have a heater on the pan so the oil is hot. I totally agree that his motor will probably run hotter oil temps than a drag motor but aluminum motors need...

Cool. Thank you again.bigjoe1 wrote:NO---- I dont do very many NOS deals. The ones I do do, they eat up pistons soooo bad I dont do anything very trick to them at all. I hope I have got rid of all my NOS customers. Most of my stuff is drag race, high RPM stuff.
