Fuel pump discussion - long.

[Rabin Rutten-James]

Hi Guys,

Just some more info on the set up first. The boost controller was set to spike to a maximum of 17 psi, the steady state boost was set at 14psi. During racing conditions, the only time they reported the "overboost" was in slower manouvers and lower rpm - which is exactly what I wanted. (I personally own a Peugeot 505 Turbo - and the newer ones have electronically controlled overboost that allows an overboost spike at lower rpms. The theory is that the injectors can feed high boost at low rpm without much difficulty - I realise the suby has no maps for max boost - but it does default to full rich does it not?)

We have no money for any fancy engine management, fuel injectors, or even boost control - so, I built the boost controller out of the best components I could with the money I had. I have to say for the money it ROCKS! It did exactly what I wanted it to, and we placed third in class - not too bad at a national event with a 10 year old car! I pushed the envelope with boost because were using VP racing fuel mix, and after talking with the fuel rep I was reasonably confident that the race fuel mix would have the necessary energy to support the higher boost.

We are seriously outgunned in our class - especially with all the cars that came from the east. We have no sponsorship - serious money anyway - and we felt this would be a last ditch attempt at placing well so that we could parlay the result into some possible sponsorship.

This was the highest boost we have ever run, but considering the competition, we figured it was worth the risk - previous to this race, I had only ever gone to 11 psi - factory protection, I just used the controller to tweek the boost curve only.

My wish list includes a wideband AFR meter and an EGT guage. Subaru Canada are actually running fully programable LINK engine management on their P4 cars - nice touch but I think they need better tuning - cars sound like they are either on or off - no low speed driveability at all. I would absolutely love to have the latest greatest toys to tweak this old car into a WRX nightmare - but speed cost money - and with Canadian money it costs 60% more. (Any donations?)

I would like to try and get this car as fast as possible, but I admit our financial resources are limited. I am currently having a website created by some people we met at the last race, but the going is slow - hopefully having something up soon because we want to hopefully get some sponsorship for 2003. The Legacy has at least one more good year, and on the right courses - it is bloody fast.

Mark would have to correct me, but I do not believe Water injection is allowed. Fuel management is open, but the air is limited to stock components, open air filter, and a 32 mm restrictor which turrns the car into an absolute dog. Any power we can get is most welcome - but I think we are having to face the fact that under the given rules, this Legacy can't be competitve in the near future..

For 2003 though, I want to go hard with the best we can to see just how good it can be. Fully optimized, and making reliable HP, this car will still be a threat.

Please feel free to make any suggestions, or elaborate on how you'd get the most power out of this engine. PS the brakes were AWESOME - easily overpower the car - thanks to KVR!

Thanks
