I'll try the 2 stroke oil next. Do you think there is any increased risk of detonation due to the use of it? I run on the ragged of detonation with lots of boost so, that's a concern.

That's basically what I was doing but, a guy that tunes many cars that was helping me out freaked out when I put it on while installing a new set of plugs. I did notice that over time it builds up and gets a little messy where the washer seals.

I tried the search function but, could not locate and answer. What lube should I be using on the threads of my plugs? I was told not to use anti-seze due to the possibility of getting some on the insulator during intallation that could cause shorting. I was told to use EP grease instead. I used EP g...

I was thinking of using a small 12 VDC aircraft fuel pump to pull fuel out of the insulated cell through a lunch type cooler with water, ice, and a coil in it then, return it back to the tank. I'd do this between rounds with a quick disconnect setup. Of course, I'd have a sandwich and some bottled w...

I'm running a Supercharged EFI SBF and cannot use an Intercooler. Cooling the fuel is not allowed on the track but, it's legal if it's done in the pits. I see inlet air temps up to 300 degrees F at the end of the pass. Would there be a benifit to cooling the fuel? My fuel is normally in the 90 to 10...

I've been running my high 8 second Supercharged SBF for 5 years using a standard volume adjustable pressure Melling pump with the FRPP oil pump shaft. I run 80 psi pressure at idle. The pump shaft goes through the bottom plate so, it's a little better construction than the normal pump. The part numb...

I was told by a friend that helps out a Pro Stock team that they run the heads so cold they have condensation on them and they also run the oil hot. It really depends on the class and type of racing you are doing.

Try this source. They make many types of valve guide seals and were very helpful to me. Their prices are reasonable also. www.valveseal.com

This is an SBF application so, I'm guessing cam twist isn't a big deal with the distributor up front. Although, running a belt drive and 80psi oil pressure probably have an effect on it. But, if the timing curve matches the retard under load; does it really make any difference?

Just curious to see what the thought is on the performance differences between crank trigger vs distributor timing. It seems to me that in a drag application if the timing curve is set optimally for either system the end result would be the same.

I've used both in the 'H' Beam style with ARP bolts and they can take 700+ with no problems. I also prefer the Scat due to the more refined finish.

I'm partial to the Vortech superchargers. I've pounded the older YS and YSi I have on my NMRA EFI Renegade car. They are very reliable units. The Vortech will also produce lower discharge temps vs ATI when comparing similar models. Although, the YSi may be a bit much for a street application. But, i...

I already have the Strange Engineering rear carbon/carbon brake kit on the rear. The pads and rotors appear to be made from the same carbon material. They are not vented and look like they were just made from a chunk of 1/2" flat stock. The pads and backing plate are one piece so, nothing speci...

There are quite a few systems out there. Racepak, Autometer, Edlebrock, and countless others. What to measure - RPM, Pan Vacuum, Boost, Wideband Oxygen sensor/s, up to 8 EGTs, Battery voltage, Fuel Pressure, Oil pressure, Water temp, Oil Temp, Oil pressure, Driveshaft rpm, Input shaft rpm, Blower sh...

I'm looking to buy the correct 3/8" to 1/2" sheet material for the application and machine them myself. I'd be suprised if the companies that sell the kits are are making the rotor and pad material from scratch.
