SpecE30 TTD?

#1

My build is almost complete now that I had my cage installed and will be running TT next year en route to comp license. I was under the impression that a SpecE30 car would be classified as TTE because I’ve read some old threads stating that, and have seen several cars with SpecE30 and TTE decals. After reading the rules myself, I interpret them that a SpecE30 car would be TTD. Can anyone confirm or deny this?

My logic:
E30 325is Base Class: TTE
Base Weight: 2885lb

-Points-
Tires: +7 for RA1s
Weight: +13 for min. comp. weight being 185lb less than base weight
Engine: +3 for modified exhaust and removed catalytic converter
Suspension: +7 for non BTM dampers and springs, replaced roll bars
Brakes and Chassis: +3 for subframe braces

Total: 33 points, which would bump up 1 class to TTD.

Is this correct?

I’m not sure that any of us knows much about TT classification. Have you asked in the TT subforum at NASAForums?

You sure you want to waste a year in TT? If you’re ready for TT, you’re probably ready for comp school.

Haven’t posted anything anywhere else yet, I thought there might be a couple people here with firsthand knowledge. I will try that if this doesn’t get me anywhere.

I have a few reasons for not jumping right into racing next year. The biggest is that I don’t plan on buying a truck and trailer until September next year. Plus there are a few safety items not required for TT that are required for wheel-to-wheel. Running TT next year will allow me to get more track experience while acquiring all the necessary items (truck, trailer, fire system, nomex, hans, etc.).

I’ll get Danny Parkhurst to help you out. He is our NASA SE time trials/spec e30 can’t be guy.

Thanks!

Been awhile since I ran TT, but why taking subframe bracing penalty? That’s for chassis stiffening devices like the Xbrace on the E36.

Oh, and I would be remiss if I didn’t say “just come race with us!” Either way, you’re still welcome in the paddock.

I did a few TT events in the last 18 mos. to do some testing of new parts on which I was not really comfortable racing until all was broken in. I ran in D simply because the rules say so. I have seen many spec e30s run in E.

Technically you are correct that the numbers do make it a D car, but it is not competitive against supercharged Miatas. It depends on whether you want to run for points or not and/or if there is someone in E who would protest your car if you showed up labeled E.

How strong is your motor? I got a dyno reclass to be able to run my SpecE30 in TTE. I would have to check again, but it was something like 145 hp and 2700 lbs still put you in TTE base class. Then you can take away the 16 points for weight and engine mods and stay at the top end of TTE in a SpecE30 depending on how many bushings you have replaced.

When I ran TT a couple years back, I also came to the conclusion that TTD is where the car should be classified… Not sure if rules are same now.

#10

Just being thorough, it’s only 3 points which hardly makes a difference. And I’ll see you at Putnam!

I just rebuilt the motor (fresh bearings, rings, non-oversize pistons, and valve job) so I’m assuming it’s fairly strong but I really have no idea. I was hoping it would be a little more straight forward, but I think I’ll look into this.

Skip TT and race. I was asked by an instructor at road atlanta why a 325is ran in ttd and a 325i ran in tte. My response was that the lsd was probably standard in a 325is and optional in a 325i. In any class or club the e30 is hated on so you are screwed no matter what.

I thought since my 325ix has viscious couplers I could run in STS legally finally. But they moved all e30s to stx to compete. The 2.5rs can still run in sts. Fuck Scca!

#12

I think the base classing difference between the 325is and the 325i (incorrectly listed as a 168hp 325 in the rules…I guess no one can TT an eta engine.) is based on the extra features stock on the 325is:

325i: TTF**
+14 points for **
+3 points for front air dam
+4 points for rear spoiler
+3 points for LSD
=24 points --> bump up to TTE

325is is TTE.

So, effectively, building a 325i to a 325is (as I have done), puts you at a 4 point disadvantage for the same exact car. Either way, after the modification points due to SpecE30 parts, they’ll both land in TTD (without the dyno reclass as mentioned earlier), and not be competitive. Whatever, the car was built for SpecE30, not TT.

If you take the points for everything, the car is a TTD. You can get a dyno reclass based on power to weight and get into TTE.

This is probably the route I’ll go
