I dont remember how much was the mid oneway, it wasnt that much!

Now on the pulley size, I am using exactly the same size as stock, if I am not mistaken it's 19 and 24T, the one that pulls the long belt is 18.

That's what I thought Dennis. Guys around here (as far as I know) use the gear diffs. We have tight tracks for the most part as electric run with gas here also. Yes I would like to see your set up. Last year the stock set up except for rear toe and springs worked for me. I'm just trying to get the car even more dailed. Show me the set up Dennis.

Isaac-

Here ya go:

Front: 10K diff, Assoc TC3 yellow springs (35lb), 50wt oil, shocks laid all the way down. Shock length 64 to 65mm (doesn't really matter as long as both left and right are the same length). 0 toe, -1 camber, 5mm ride height. Castor is a one thick and one thin spacer behind upper arm.

Rear: 5K diff, kit rear spring (long silver one). 30wt oil, upper shock position: middle hole. Shock length 66mm. 3 degree rear toe. -1 camber, 5.5mm ride height. Camber link, lower inner hole on tower and upper outer on hub.

Tires: 45sh front, 37sh rear. Tire diameter 61mm.
Body: Protoform Stratus

Notes:

I ran the above set up at our season opener so the track was a little "green" (plus it was the first time our track allowed foams to be run on nitro sedans). Also, since our average club turnout is usually about 140 entries (this is just for nitro days, electric days are just a little below that), there's not a lot of time to test.

From what I can tell, the car had a tad too much on power and off power push for me, but the car was very easy to drive (plus it was competitive) so I left it alone. If I had more time to test, I probably would've made some simple changes (eg, use softer front tires or harder rear, maybe try a rear sway bar or stiffer rear springs to free up the rear end a little -- just to get it to rotate more).

If you notice my set up above, I didn't list what settings my droop screws are at because I didn't use any. Our track is a parking lot, so it tends to be bumpy. Thus, I allowed the shocks to be at full travel and I only used the droop screws to set tweak.

Hope this helps,
DT

DT!!! whoa that's almost my set up. The changes.
Harder rear foams like 40 shore (double purple front & purple in the rear), Assoc. purple springs front and Assoc. gold rear springs and 3 degrees rear toe in. I'm using 30K in the front and I think I'll go down to 10K. Oh I used the stock shock oil fron and rear. I might try something thicker than yours. 80wt front and 60wt rear.

psycho--

Yes, I'm planning on being there, but the kids have basketball playoffs and little league opening day is fast approaching (wife is on the board), so I have to beg..er..I mean "discuss" it with her to make sure.=)

Isaac--

Yup, that set up is actually my rubber tire set up (which worked really well for me). Again, this is the first season of nitro where foams are allowed (in sedans that is). So, I'm sure it's going to take a few races before we really hit on a "killa" set up. Honestly, I feel the car is really close right now (at least for my driving style). Just a few tweaks here and there and it will be "perfect".

When Mike Swauger (factory Mugen) looked at my car, he thought that the diffs may have been a little too "light" for foams. Normally, if the fluid is too light, your car tends to "diff-out" (meaning it unloads too much -- which makes the car handle a little erratic while cornering). Surprisingly, I felt the car was really stable and predictable, so I'm going to leave it alone.

Yes, I think the large difference in shore ratings between the front and rear tires had quite a bit to do with the push that I had. But, as I said earlier, the track was "green" so we were kind of struggling for traction in the morning practice. Once they resprayed it, traction was great -- but I didn't have the time to test other compounds. So, I pretty much just ran the car the way it was.

Good luck,
DT

Dennis,

your rear tires are too soft, that's why you have a push.
Try 40 in the rear, they also wear better

Stefan --

Thanks, I think so too so I will get some 40sh rear and some 42sh fronts to try this weekend (I'm banking that my begging the wife will be successful).

Exclamation Kawahara negative diff

I just got a neg. diff off Ebay and it looks brandnew and smooth.
I got the original instructions with it, which are in Japanese.

I understand how the thing works, I have one question though.

There is a small hole in the aluminum housing, where the clutch shoes are.
In the manual, there is quite a long comment about that hole, BUT I CAN"T READ IT :-))

Can somebody tel me what that hole is good for?


Thanks

The holes in the negative diff is for cleaning. Spray some CRC in there to clean.
