Howdy y'all!

I've gone ahead and invested in a Wright gearbox from the states (imported by Classic).
Now, I was planning on getting a 3.88 pro street box with a super diff, but ended up accidentally with a 4.12 freeway flyer. By my understanding they're the same bar the fourth gear (in the flyer) and the superdiff (pro street) and final ratio.

I'm coupling it to a 2276 with high comp, cranky cam and 48's, and I want it to be a tough street car, and I don't plan to do agressive burnouts or anything like that.

I'm now thinking of keeping the freeway flyer, as it could be better on the street for my needs.

Basically I'm asking y'all to throw your opinions in (if you know your way around a box) to help me decide whether I'm better keeping this freeway flyer or should I swap I back for the pro street. The only real reason I was going to go pro street originally was due to the fact that I thought a super diff was an LSD, which I've now discovers its not.

Anyway, opinion away good people!

Cheers,
Ollie

depends on the cam if its for low down torque ( like mine ) runs great

or you have a hi reving motor needing to go over 3 or 4000 revs to get it to move

by the sounds of it you will be reving the engine to get it going

Did you try referencing the part number on rancho site for gear ratios?

Thats a huge cam for a street car.
It won,t play until you see 4500+rpm, with a standard ratio box? mmm best rethink your cam.

As Daimo says, what are the gear ratios? Thing is the Freeway flyer is the 4.1 diff and the Prostreet is a 3.88 diff. The 3.88 is a taller ratio than the 4.1 so more of 'freeway flyer' than the 4.1...??? You need to know the other ratios to make any judgement. The seller or manufacturer should tell you. Why don't you use a local shop? At least you know what you get.

Yeah I was going to go down this road and this came up at a good price, so went with this option. That and I'm trying to do this on a decent budget and building one up was looking to be super pricey.
I'll do some research to find out the ratios asap

I would be getting it as close to correct BEFORE you purchase....trying 30" diameter wheels to get the gearing right is a bit silly.

Hmm, yeah - definitely suss out all the ratios I reckon.

I know from a past incarnation of gearboxes with Jezebel that changing from a 3.88 to a 4.12 AND NOTHING ELSE makes a huge difference to things.

Have a play around with the Bajawes's excel dyno - can give you a really good picture of the difference it makes in revs, including different tyre sizes.

My 2 cents all the power in the world is useless if you can't bitch slap it 24/7!Correct choice of quality ratios and parts and an expert build(Dave Buttler is my choice and many others).But it's the expert build that makes all the diffrence.
