Your right, the oil pressure switch controls a relay which operates the pump. There is a manual overide to prime the system for starting (if required).

If you are going to use your car in competition with an electric pump then, according to CAMS, you will need to have some form of cut out so that in case of a crash the fuel pump stops if the engine isn't running. CAMS don't want fuel being pumped over hot exhausts of shorting electrics. In my case the pump is hooked up via the oil pressure sender - no oil pressure no pump. Not strictly by the recomendations but it works. CAMS suggests using a cut off swith (impact sensor??) from a LPG vehicle to do this. Then again, I have not been required to prove that I have complied yet.......... On the pump side, I am running a Facet pump under the boot floor to feed my twin aisans with no return line. Tried a Holley Red a long time ago and pissed it off as it kept starving for fuel. The car would just stop until I sucked fuel through the system. After this I went back to a Facet.

I would have thought that the biggest gain in using an uprighted engine would be the ease of fitting side draught carbies in early engine bays. Just my theory though...

Ditto. Last a couple of year in my case.

I think Fast Fours and Rotaries had an article on an Escort that had something like this done to it. Don't know what edition it was in. I think it was a track car.

don't know about 8500+rpm but I usually have the shift light on (set at arond 7500rpm) for a full motorkhana with no problems :S

I swear by the Wade 169 in a 5k. Enough grunt to get oversteer in 3rd gear coming off corners while autocrossing but enough torque to be driven easily. Still don't know why people insist on changing to solid lifters when the standard hydrolic lifters allow big revs and you don't have to adjust them :S

G'day Rob. Long time no see since you left "mexico".

Sounds like you want to do what I have sorta done. I'm running a KE20 with a 5K. It is running a Wade 169 grind which I have lost the specs for :sad: This cam allows me to rev past 7000rpm (have seen it past 8000rpm, but that was on the factory tacho which was optimistic). I'm still running the standard head but on a previous 5K port matching and a compression hike (shaved heaps but still able to run "super" back in those days) made a big difference to the torque. Current 5K is fitted with a 3KB manfold and a pair of standard Corolla carbies (bigger venturies) and 4 into 1 extractors and a 2" exhaust plus a few other mods. The above combination made around 3 seconds difference a our local autocross track over the standard 3K. Works out to be around 1.5s a kilometer quicker. Also at the last Challenge of Clubs, I ran 2nd outright in a field of 65 cars, behind a mini special so I think the combination works quite well.

There have been a few times when I wished I had a catch can when competing in motorkhanas as it sucks driving through your own oil smoke........... Only happens at max revs and on long right hand corners.
