mindspin311 Posted August 24, 2018 Report Share Posted August 24, 2018 If I had the money, I would dump my BMWs and have @vtjballeng help me build me a couple Nissans. 2 1 Quote Link to comment Share on other sites More sharing options...

Yea there's nothing fun about a 2800lb e30, probably means they added ballast to it. Even a Spec E30 is 2700lbs with driver. Quote Link to comment Share on other sites More sharing options...
mender Posted August 24, 2018 Report Share Posted August 24, 2018 2791 lbs to be exact. 1 1 Quote Link to comment Share on other sites More sharing options...

mender Posted August 24, 2018 Report Share Posted August 24, 2018 Oh, they're much lighter; that's the "official" Champ weight in the swap calculator. 2791 lbs is exactly the number needed to allow an M50 swap with no points. Most E30s are probably around the 2400lb mark as raced, as you said. 1 Quote Link to comment Share on other sites More sharing options...

Ok...because I think we are going to get our new Bird under 3000 w/ driver. 2 Quote Link to comment Share on other sites More sharing options...
mostmint Posted August 24, 2018 Report Share Posted August 24, 2018 Whatever. I’ve raced one, been on the podium with one, they are fine cars for what we do. There are a few premiere tracks like VIR that really attract them. There are some that belong to good teams that I can’t catch with the Saturn but the rest are Blocking My Way. 3 Quote Link to comment Share on other sites More sharing options...
Jab31169 Posted August 27, 2018 Report Share Posted August 27, 2018 Yea you always see a bunch at VIR. I was just happy to see a good number of e36's. I still need to figure out how to get my stock M50 to put down 191hp at the rear wheels. 2 1 Quote Link to comment Share on other sites More sharing options...

I'd like to get a clarification on this as we've held off on putting a silicone boot on before our throttle body since its after our MAF.

You were super clear, the rule book states differently. The motor was rated at 189 from the factory at the flywheel. So with the around 15% drivetrain loss thats around 161 at the wheels. Does 30HP sound reasonable with just an air filter, exhaust, and some tuning? Or do you need to crack a motor and build it from the ground up to get that number. What does acceptable number even mean? I just wanna figure out how to get the same number out of my M50. I'd guess our motors range in the 170 to 180 with the mods you listed, outside of injectors as they are just cleaned and serviced stockers. But hell, what do I know, our motors cant make it more than 30mins in a 24 hour race 1 Quote Link to comment Share on other sites More sharing options...
Technical Advisory Committee Ray Franck Posted August 27, 2018 Technical Advisory Committee Report Share Posted August 27, 2018 What acceptable means to me is when I look up hp numbers of what different modifications can achieve . On that engine I dont have a problem believing 25 to 30 hp can be gained with non restrictive air to the throttle body ecu tune, injectors and freed up exaust . A fresh build and some dremel porting is also alowed by the rules. So about 30 hp gain doesn't raise the haires on my neck especially if you have the best in the bizz doing it . Also 15% drive train loss is just a shot in the dark or a just about . That is why I ask for opinions from others cause I dont know it all but I can smell a rat when I see one .. 1 Quote Link to comment Share on other sites More sharing options...

Whats up with injectors? I can’t see how anything with them would be worthy of an improvement for a stock motor? 2 Quote Link to comment Share on other sites More sharing options...
Team Infiniti Posted August 27, 2018 Report Share Posted August 27, 2018 How would a 2700 lb e30 with 180ish to the wheels do? *Asking for a friend* 2 Quote Link to comment Share on other sites More sharing options...

Bigger injectors = more fuel. More fuel = more rich. Being rich is basically the same thing as winning. Winning means you have more power. So by the transitive properties of stuff, bigger injectors means more power.
