New Weight for E36 325 ITS?

[snowmann]

I like how are target range for power to weight is in the neighborhood of 15... however our car with a bmw advertised hp rating of 135, and a ITS weight of 2600 puts down a number not so close to that 15...



you do the math...

All we can control right now is what is newly classified, re-classified or to use PCA's to try and return some class equity if there is an glaring error...IE: weight or an RP.

If you are talking about the E30 318is - how does ITA sound?

I think that makes more sense then ITS dont you? I mean obviously ITA cars aren't far off of the ITS crowd but still that sucker is just an under-dog... And doesnt the z3 even run ITA? all other cars with this very same motor run ITA... this car somehow got thrown in ITS? doesnt make much sense... We race Midwest Council as well, There are a few ITA guys that will follow, if not lead the top ITS guys at BH farms...

Right now we are just having fun getting out there and running

IIRC, the 318is (1991) was recommended for a change to ITA. Darin can verify but if not, a letter would get the process rolling. Seems like a no-brainer. Betting it would be around SE-R/NX2000 weight.

I'm pretty sure that we moved this one, at a weight similiar to the Z3... I'll see if I can find the exact date of the recommendation... NO one on the ITAC felt that this car belongs in ITS, if I recall correctly... (a thing that's a bit iffy these days! )

Not to sound too bias'ed but the newer motors have a higher hp... they call it the m44... (whats in the 1.9 z3) so really seeing as how the z3 shares e30 chassis components id almost assume that the e30 should weigh as it does in ITS...2600

I think all the people racing the M44 would agree that it doesn't have the potential that the earlier engines had. Try tuning the two piece intake manifold that's not allowed to be matched in the middle, seems like and instant power drain right there. Also from experience I can tell you it doesn't like WOT below 4k rpm but will bog down when excess throttle is applied. I think Noam said it best when switching from his Honda Civic, that he wasn't used to the lack of power from the M44. Or you could be in the e-36 318i which is at 2840 lbs or TEN pounds less that the ITS e-36 325

Even though I haven't been able to find it in my notes (I was looking in 2005, and apparently it's in 2004...), I checked with SCCA Tech and here is the response:

Darin,
This was in the 2004 recommended items:

Item 1. Based on recommendations from the IT Advisory Committee, the Club Racing Board is recommending that the 1990-91 BMW 318i/is be reclassified from ITS to ITA.



Regards,


John

I'll go back and look to see exactly when this was recommended, and what the recommended weight was... I think it should show up in the 2006 ITCS...

OK, I just received a note from John concerning this. The 318i/is Twin-Cam 90-91 was recommended for reclassification from ITS to ITA at it's ITS weight of 2600lbs... That happened to be the correct weight, based on the IT classification process...

Hope this helps! (in more ways than one! )

Should be competitive now!

Is this going to be in affect in 06? Would like to get m. council in on this as well

Darin,

I just looked at an '02 GCR (just happened to be the one on the desk), and it's got the '92-'94 318 (E36) DOHC listed in ITA, at a weight of 2840#. It didn't say "318is", but all the specs look the same. Oddly enough, there were no valve sizes given for the ITS version or the ITA version. I'm not a BMW guy, so I don't know there is a difference between the '90-'91 cars, that are slated to move to ITA, and the '92-'94 cars. If the '92-'94 car is one of the ones that's part of the 'mass PCA adjustment', I'll just be quiet, and go back to reading my VW Bentley manual. :P

Mike,

The fact that some of those top E36 cars have survived ARRA post-race tech, notwithstanding, you might want to re-think your above comments. You are, in pretty much so many words, calling a LOT of folks cheaters. That's a pretty serious allegation, and something that shouldn't just be casually thrown around. I have no idea what the prep level of your car is, or who built it, but unless it's a 10/10ths effort, it's pretty disingenuous to hint that the top guys are cheating. And if you think that restrictor plate 'suddenly appeared' this year, you haven't been following this site much.

As far as how to get the weight up, you just add lead. The 100# max ballast rule has been lifted.

I won't speak to specifics, but I can tell you that 15 is just a number that was thrown out there as an example. Don't read anything into it.
