Why is moton so gay

[rbsileighty]

The extra weight is in the motor and transmission. There's at least 100+ lbs. of difference between an SR20 and an RB25. The gearbox is another 20 - 25 lbs. or so. The gearbox weight doesn't matter too much due to it's location, but the frontal weight on the 240 is the most crucial weight in the car. The less weight you have in the front the less you are going to fight the McStrut and tire disadvantage.

Carbon fenders will save nothing. A steel 240SX fender weighs hardly anything. The hood will save weight, approx. 30 - 35 lbs. but you can do that regardless of what engine you run. Same with the battery.

Then if you want to get involved in weight placement, the SR is superior yet.

The only benefit of the RB is reduced cylinder pressure and a benefit in spool characteristics. That isn't going to account for much in terms of time on a track car unless you are pushing more than 250whp.

I see where he's coming from... but coming from a RB track car owner it's not a really big deal to run a RB. I can run D and B here in MI b/c there's no one really running the class and I just like tracking my car Granted I haven't run mine in the class yet but I could with a little work... been busy with T2

I agree from what I understand NASA should allow you to be more competitive, but I haven't run NASA so I couldn't tell you... like I said I run T2 with work's 350Z so my car is really just a toy I can take to the track and drive on the street.

Basically I built my car for me and found a class I could race in if I wanted extra seat time... unless you're out for blood I'd recommend the same.

Don't forget you have to get your comp license before you can do anything...

Check the links in my sig... you can look at my setup. Your power to weight shouldn't be a real factor due to D prep having a min weight of 2700lbs, which I think I'm around if I recall... you'll have to run a restrictor in either class so a knowledge in fluids will be your friend here (40mm for B, 30mm for D)... if you know someone who was on a college Forumula SAE and worked with the engine they'll be able to help a lot working around a SIR (single inlet restrictor). Yes you'll be a bit more front heavy than a SR, but it's far from a pig... if you have a good suspension setup it's not an issue you'll have to drive around that's for sure.

Just don't skimp on your cage... saved my life once in the T2 Z (no lie).

Hope this helps...

Oh... and a lot comes down to the driver too... improve your own skills and you can beat a lot of things in an "underdog" car... I'm not an exceptional race car driver... there are tons better than I am I'm sure, but at a OTD I managed to tail a stock C6 in my old stock 05 G35 6mt sedan w/ stock tires until he finally waved me by and I continued to pull away from him... that car should have been WAY faster seeing as C&D pulled 10 sec faster than my times in a C6 on the same track... just thought I'd throw that out there

It's not a huge deal, but if you are competitive you'll want to maximize your advantage.

I see what you're saying... but I really don't think with a good suspension tuning/setup on both cars the SR will be a huge adv if the cars are both the same weight... I think a good driver could make either setup just as competitive as the other. I think an entirely different platform would be a better argument... like my S2000 would be a better start than my S13 for example
