If he is, and you do the measuring, guess who gets the blame.
The key is going to the right builder. The nice thing about that shop near Ben's work is that they've been in business forever and they've done satisfactory work for Downing.

 

I bought a set of Mics about 3 years ago and only spent around $400 on them, then a 300$ Dial bore gauge set. The dial bore gauge won't go down small enough for the miata engine, Bought them when I was building a 2.3 ford Lima. Had a shop machine a crankshaft and give me their measurements which matched my cheaper set.

 

My new R&P showed up today
43 ring gear teeth, 13 pinion gear teeth.

 

3.307?!?! awesome.


its funny how we all want longer gears.

 

Nice Ben .. when are you going to get it Cryo treated? I'd like to get my 3.6 that i'm sourcing from mazmart Cryo treated.. maybe get a few of us together and get a discount?

 

Yeah, the fabled 3.31. Will be baller with a 6 speed I think.

There's a place in N GA that I was going to send it to be cryo treated. I'm in no rush for mine, but I've got at least 1 other to send out in the short future. When we're building diffs for high power cars, I'm going to make cryo treatment standard.

I'll poke around on getting a batch of the 3.63s treated at a group rate.

 

Thanks Ben !

 

I still need to get that mani and downpipe from you.

So how is the whole build going

 

Looks like I can get them treated for $70-75 per set in bulk.
Standard price was $100.

 

I love how your car feels currently...and have a real hard time envisioning with 40-50% more power. Should be able to steam-roll that Ferrari you promised to eat!

 

Yeah, it runs pretty strong. Despite some slightly disappointing numbers on the dyno. Still trying to decide if I should go ahead and put those cams in.

Ferrari's a no go after he needed a $14k clutch

 

 

supercar = super expensive to maintain.

 

$14k? really? damn.

 

A bit of automotive legend is appropriate here I believe. I have heard the story, but might as well quote wikipedia

"Ferruccio Lamborghini went to meet Enzo Ferrari at the Ferrari factory to complain about the quality of the clutch in his Ferrari 250 GT[2]. An infuriated Enzo Ferrari sent him away telling him to go drive his tractors because he was not able to drive cars. Lamborghini went back to his factory to have the Ferrari's clutch dismantled and found that the clutch in the Ferrari was a product of the manufacturer who supplied the clutches used in Lamborghini tractors. Lamborghini installed a stronger clutch from his factory's warehouse into his Ferrari and solved the clutch failure.

Furious with Enzo Ferrari's arrogant and aloof manner, Ferruccio Lamborghini promised himself he would never own another Ferrari, and would beat Ferrari at his own game, by creating a superior sports car of his own"

OK thread jack over. Very nice build!

 

looks like there is a chance at seeing the 3.308 gears again..

Holy **** those gears are expensive. Damn. Like 200 bucks buys any richmond gears out of summit racing.

 

Yeah i'm sure mass produced gears like GM and Ford are going to be a lot cheaper. When you are making small numbers like this the price goes up.

 

I wish Bill luck getting 50 orders. It would be nice, but I don't see it happening. If it does go through, Mazmart can help out with a correct speedo drive gear, as Bill doesn't have a solution there.

 

wow, I'd love to have those gears, but damn...north of $500 is way too high for my cheap ***, and I mean waaaaaay too high.
Where did you get your Ben? I've read rumours of these being found in some rare RWD 626's, I have no idea where I read it.
