Do you have 12V to the Mefi? If you switch the ign on and the fuel pump doesn’t run… that indicates the ecu isn’t powering up

Air to air in the back of a buggy can be pretty inefficient. You need airflow to make them work at peak efficiency. It will be better than nothing but certainly not ideal. Keeping it away from motor and exhaust heat is critical. I wouldn’t mount it the way the Subarus do. All that engine heat is...

I agree on the calling a cam company and giving them what you want the motor to do for you. They will steer you right every time. TSP has be good for me but I don’t think there is really a bad company out there. Example: If you want the best dyno number at 6500RPM they can get that… if you...

I’ve never quite understood why people make the On-off ranges so wide. The goal is tight temp control, not a 20-30degree range. Trying to cool the water from 200 to 185 takes a lot of air. That’s why the fans run so hard. Might consider putting the trigger range tighter together, like 205-200...

2x 15's = 21. You can calculate the effective thickness of 2 or more same diameter shims in a stack by: Sqrt(shim1^2 + Shim2^2) so, sqrt(15^2 + 15^2) or sqrt(450) = 21

LOL, not too familiar with that one but they sure did get a deal! Wish I'd have know n it was going to auction, would be good spare parts

Car is having some other work done so this won't happen until Sept timeframe

Thx GM

I'm adding a gear indicator switch to my gen1 S4. I'd like to use it with my Holley Dash, has anyone done this and willing to share the details?

Isn't overheating a sign of a head gasket leak too?

Blue Sea Marine has nice bus bar choices.

Vaseline with some graphite powder

Even without the beach or the hill, there is a lot of sand all around town. Would be fun to have some Padla Trax to get a little more bite. If you are not going to be driving a lot on pavement you'd have fun. I run 37" BFG KR3's at 10psi.... still gotta watch where I stop.

Thermostat is a process control tool. You want your engine at a single operating temp under all conditions. The thermostat adjusts water flow to keep the engine at a set temperature. Idle, low energy into engine: Thermostat closes to let the engine maintain heat WFO: max energy input...

yes. They do make restrictor plates you can buy from Summit. 3 or 4 different hole diameters that work with the stock gasket. Or, just pull the guys ot of the thermostat and keep the plate.

Good comments on the pressure topic. My experience is that you can overcome anything with enough fan. If you are counting on natural air flow to cool you are going to end up with challenges. I think the more you lay it down the less pressure has an effect on the fan efficiency so if you were...

150psi is standard. Tuning with N2 is not the best way. The pressure is really there to manage cavitation. Less pressure = cavitation at slower shaft speeds.

There is not a gasket IIRC. Its a seal on the thermostat itself. I think you have to buy a thermostat to get it

Update: It was a combo of an old starter and a dicey battery. New IMI-101N and a new battery she fired right up.

Thanks Wes.
