So after the SCCA runoffs this year a buddy and I started to look at the STL rules. We both race Honda's but the club we race with runs a bracket system for car class. So we started to compare our bracket with what is legal in STL. We have a few things done that wouldn't be legal in STL. 8inch wide rims, 95 sub-frame in a 99 civic and no restrictor. Outside that we would just be very under-prepared.
But we found one odd rule for Honda's. The B17A1 doesn't require a Restrictor? Same HP as a B16 and a tiny bit more torque. Is there something i am missing? I ran a B17 for a few years racing prior to the ITR motor we have now. it was a very strong little motor. This year We used it 1 weekend and a fresh B16 the next. Same B18 GSR cams in each, same ITR intake. The B16 had better track and weather but was slower.

So am i missing something? This is all for nothing as well. I cant afford to tow to the states to race, and i dont see any Canadian clubs bringing back the Canadian Runoffs. So more less just discussion.

 

Step 1 - delete this thread and keep secret
Step 2 - get b17
Step 3 - become Ayrton Senna of STL

 

im a honda challenge guy so i havent taken a deep dive in to the stl rules...well i mean i tried to once but i gave up due to the complication lol

but yes, i believe i saw some discussion about this when the restrictor rules got dropped on the hondas. i think a lot of the issue is that it is pretty difficult to find a b17 these days imho, but i do believe it has now become the silver bullet.

 

You are reading the rulebook correctly. As of the November 2018 GCR, the B17 motor can be run without a restrictor in STL.

 

Well atleast i am not totally Crazy... lol.
So everytime i find one for sale should I buy it up and sell it state side for many many pennies more? lol. We might actually go get one this weekend to replace the exploded one. lol.

 

So pardon my ignorance here, but is the B17 that powerful a motor in race trim?

 

good luck finding one (running or not)

 

its not that its powerful, its that it gets to run un restricted vs. all the b18's i believe.

 

I know the idea of a restrictor is unappealing, but in the world of racing output is all that matters. With all the cheap engine mods available for the B18 I would be willing to wager that you could build a restricted B18-powered car that produces the same output as a B17-powered car for nearly the same money.

There's also a letter out to the Competition Racing Board asking to remove the restrictor for the non-VTEC B18s to give them a better chance against the cars that produce more power from the factory. If that goes through there might be little between a well-prepared B18, B17, and B18C motored STL car: The non-VTEC B18 would be allowed to breathe better, the B17 car would get a lower minimum weight due to its lower displacement, and the B18C would run restricted with limited head porting.

 

The STL Table A is put together friggin' awful. I've sent a couple letters and not even gotten a "Thank your for your input." If you are one to read the rules AS THEY ARE and don't have the memo the SCCA issued on the Honda restrictors (MA 18-02) you'd be able to run the B18 GS-R engines (C1 and C3?) unrestricted in STL...

"Acura/Honda B18
(except C engine)"

Okay...doesn't fit there so...

"Acura/Honda B18C (JDM Type R), B18C5 (USDM Type R), B18C6 (UK and Euro Type R), B18C7 (Australia Type R)"

Well, I have a B18 but it's not JDM OR a Type R so I'd say I don't have to run a restrictor. Why can't/won't they just change it to "Acura/Honda B18C ALL VARIATIONS" or something?

 

stl keeps the gsr neutered with the stock oem intake manifold anyway so the "r" stuff got restricted ( at least i think im reading it right?). this is exactly why i went to honda challenge!

im about to submit a rules proposal for H2 to allow the gsr to run type r cams at a 50 pound weight penalty. if that manages to get approved, you could do a gsr at 2400 pounds, gsr with r cams at 2450 or a type r motor at 2500....simple and pretty damn equal!

 

Or could just plane cheat like everyone else, unless you are running a car that is going to the run offs.

 

to me its ridiculous they have rules with the classes being so thin and with the top guy pretty much yarding everyone substantially. all the rules/classes probably made sense in the early to mid 2000s when they were able to field 20+ cars or so but these days its a diff story.

they should just cap everyone @ 200 whp and run watcha'brung
