Not sure what ratios are in there. What kind of speed does that come in at? Maybe putting videos side by side may give a fell for how fast I was going. I need to do some work on figuring it out when I change the clutch, it is pretty well smoked after my last run. I was about half throttle in 4th, but it was fast enough for the first time on the mountain. Were you running the blue RS? I think I have awefully high gears in transaxle. I am thinking about building one with lower final drive and closer ratios since I have a 5MT (I think) in there, just not AWD. Also, want to add a limited slip or locker of some sort.

Yeah I had the blue RS. I have factory 4.11 gearing though, and with my tires it comes out to about 103 at redline in 4th. What is your transmission out of?

Being a 5spd, I think you should be able to use the gearset from a 2.5RS. The RS uses close ratio gears and a 4.11:1 final drive. Even if you can't, the front diff shouldn't be any different than an AWD trans. If that is the case, you can get an OBX helical LSD for less than $500, or step up to an old skool JDM suretrac front LSD. Phantom grip should have an application as well....though I can't really recommend it.

If you want an easy way to know your speed just throw a handheld gps in there

looks like a fun project!

Not sure if it would work with the tree cover as a few guys have gPS based systems like Trackmate and they do not work. Also, I am not sure if I want to take my eyes off the road long enough to look. Maybe I can get one within view of the camera. Thanks,
Steve

Just southwest of Wilkes-Barre headed toward Rickett's Glen State Park.
Giant's Despair Hill Climb is next weekend in Wilkes-BArre, and I will be racing it there if you want to stop by. Hoping my clutch will be here in time.

Awesome! I'd love to know/see more on how you make the tranny work in a mid-engine setting, which one you used, etc. How long is the package from the front of the motor to the back of the tranny? -or- What is the shortest length space that package would fit in? I've tons of questions!

Enjoy!

From front of engine to back of shifter rod it is 46-3/8". It just moves straight back with the same orientation as in a front wheel drive. Trans is from a FWD legacy 5MT. The tough part is the transmission shifter linkage as it is one long rod from shifter a universal, and then a 30 degree bend and into the standard location like the formula vees run.

Hand designed and built chassis. Front Camaro spindles, rear are from an SVX. All tied together with race car components to reduce cost and weight. Not a VDUb part to be found on it.

If the FWD 5 speed is umodified you might consider at least changing its final drive to 3.9 if not 4.11. For the most part the FWD five speeds were 3.7:1 final IIRC!

I can send you an AWD front diff (open type) to test fit and confirm compatability inside the FWD trans. That will open up a few choices for LSD's you can work with!!!

PM me an address.

The front wing looks strong!!!! You sir, have some incredible fabrication skills.

did i miss where you said you built from scratch the chassis?
or is it a hybrid chassis from some other class?
I would like to find one that allow usage of our awd drive train.
that way I can get a "high gas mileage" car..

Had some trouble Saturday, got to 57.0 and got under a minute which was my goal. Found out if you plug in both test connectors, it will bypass limp mode and run like a demon. My best was 51.56 and was next to my last run.
On my last run, I was hauling up until the last turn, so watch at 1:25 or so.
Also, frank videotaped one run from outside, which was not my best, but can be seen here:

86 cars, probably in the top 30 and missed a trophy by .3 seconds.

I am 99.9% sure they are the same but I can't find the info.

Even if not he could use an AWD transmission with a welded center differential and plug on the tailshaft. Thats what the dune buggy guys do!

True......but the FWD trans has a couple other interesting destinations where a modded AWD trans wouldn't be practical (or allowed by pesky rules).

Maybe someone can run a crosscheck on part numbers.

I'd place money that the diffs are the same...however I know you can just weld the center diff in an awd setup and run that way.

I'd be QUITE interested to see your shift linkage setup at the rear of the trans.
