I definitely want to eliminate all the extra BS in the rules and don't want to go though another tech bitching session about inner fenders, horns, seats and other non-essential BS. This is what I proposed originally, at least for BPG:
1, Current turbo/weight rule 3300 82mm and smaller 3400 83mm to 88mm 100# penalty for T5 flange
2. Current tire and rear suspension rules
3. No liquid IC's
4. Current exhaust system rules
5. Regal body required stock firewall location with stock frame. Modifications for tire size and x-member clearance allowed.
6. No NOS or additional injection/spray of any sort in or on the motor, turbo, IC, drive train etc.
7. Gasoline only
8.Car must have all applicable safety equipment for speeds and times
A bunch of people have piped up about TSM/TSE combos being allowed and here are my suggestions:
INTENT: This a heads up class for 81-87 Buick regal bodied single turbo Buick V6 cars running stock style rear suspension and a 10.5" tire. The class is to be run on a .400 pro-tree and on a pro-ladder. No minimum qualifying times with a quick 8 format. Car must have all applicable safety equipment for speeds obtained and must be able to pass host track safety tech.
Class minimum weight is 3100#
1. BODY: 1981-1987 Regal body required with stock firewall location and stock frame. Frame modifications for roll cages, safety, tire size and cross member clearance are allowed. Functioning headlights and taillights required.
***Are we going to allow cutting the frame after the front suspension and allow pin on front ends? Do we want to put in wording for it or just leave it as is and see if someone shows up like this?
2. EXHAUST: Must be functional and extend to the rear axle and away from the body.
3. FRONT SUSPENSION: Must have stock mounting locations. Any aftermarket bolt on part is allowed. Rack and pinion conversions are allowed
4. REAR SUSPENSION: must maintain factory mounting locations on the frame. Coil over conversion allowed, sway bar and panhard bar modifications are allowed. Must maintain factory 4-link arrangement. Any automotive type solid axle housing allowed.
5. TIRES: Slicks w/ sidewall designation up to a 29.5” x 11.50” -15” size tire w/ a maximum measured footprint of 11.25” is allowed, W tires are allowed. ** Phoenix Brand 11.5”standard and W sidewall designation tires are not allowed do to tread width restrictions. DOT street tires w/sidewall designations up to a 30.0” x 13.50”-15” size tire are allowed
6. TURBO: Only one allowed. Any commercially available turbine or compressor housing is allowed. No external modifications or welding is allowed. No hybrid or custom housings are allowed. Commercially made housing must be available by November 1 of the prior year. Maximum turbo size is 88mm to be checked with a plug**See below.
7. FUEL: Gasoline fuel only, no additives, alcohol, or nitrous oxide injection allowed. No additional injection/spray of any sort in or on the motor, turbo, IC, drive train etc.
8. WEIGHTS:
3200# for any turbo up to an 82mm
3300# for a 83mm to an 88mm turbo
ADDITIONS:
-50# for any stage or aftermarket block that utilizes a 14 head bolt configuration
-50# for any motor over 250 CID
-100# for a T5 flanged turbine housing
-100# for a liquid IC to be assessed with car at full weight and IC reservoir full ** I don't care one way or another if liquid ICs are allowed. This is a pretty stiff penalty because it is going to be over whatever the car already weighs.
DEDUCTIONS: (Car can not weigh less than 3100#)
-100# for iron production heads no stage 2.
-100# for turbo smaller than 71mm
This should keep all the current participants at the same weight and allow new combos to be competitive. Your typical TSM car with a 76 mm turbo would have to weigh 3200# and should be very competitive at that weight. There are no weight breaks for a 109 block but weight penalties for additional head bolts and CID which do affect performance. If you take Dave Bamford's car and shave it down to 3100 with a 70mm turbo mathematically it could run 8.84@153 with the same TSM combo so that should make things interesting. These are pretty simple rules with the bare necessities so if I missed something please speak up. I know I re-worded a lot of stuff but these are essentially still the same rules from this year just with added weight breaks for different combos. So far we have BPG and Norwalk and Bill mentioned Cecil. The Q8 format should make things quick and easy for the race promoters and to date we haven't had more than 8 cars show for an event on race day. It would be nice to have a points series with sponsors and payouts.
So lets hear the opinions and suggestions!
PS: Cal I put a few calls into you give me a buzz.
