My car is getting retuned today...

[FAHHQUE700]

it's called a tip table, and sometimes the tranny can have something to do with the tune. I have never tuned with any of the stuff you guys use. Just FAST, EFI Solutions, and the SCT Pro Racer Programs. But still it's all pretty much the same stuff.

One question for the owner of the car. Why don't you have the new tranny's gears face plated? it will still be streetable unlike building a proshifted tranny. And it will handle anything you can throw at it. Plus it's 10x quicker than a normal tranny. The only draw back is that it requires more maintainence. But look at it this way you drive a 600hp+ honda.... it's gonna need alotta upkeep.

700, hell even 600hp is very impressive on a single 255 Walbro, but the only thing is running 100% cycle duty on those pumps is harse. Just one recomendation to the tuner, or anybody who is using a pump that only needs a little more, or maybe a little more security can use a pump driver which is like a voltage amplifier. A bigger pump is not always the answer... to make it simple you have a 12v operating system. @ 12v a 255 LPH pump theoredically should run 255 LPH running a pump driver @ 17v produce up to 385 LPH WITHOUT killing the pump. And actaully Walbro has done many test running the pumps @ 17v with no problems, no current drops, nothing, but great results. Having too small of pump can also kill your injectors. Running those late night street races, running high voltage ignition systems, and even car stereo system robb your fuel pumps voltage... maybe your getting 11v-12.8vdc to your pump... well, it's killing it self to keep up with the injectors, and at this time, most of the tuners will have the injectors hung open in WOT @ 100% cycle duty, now your killing your injectors. Oh yeah... all the excess work from your pump & injectors causes more heat soak in the fuel. Fuel likes to be cold... this helps out with that too...


I know, I kinda went overboard on this, but oh well...
I'm only trying to help. I like to see shit like this...

PM me for more infomation.

if i remember correctly there is an external relay and larger gauge wire to keep the pump voltage from sagging. also there are custom lines ran as well and the inj aren't maxed (thank god).

you're absolutely right and anyone thinking of making 450whp or more should always consider the pump mod and make sure to have an the next larger inj than you think you'll need. pushing inj at very high duty cycles is like playing a sub at full blast on a smaller amp for long periods of time w/ small gauge wire...the amp will get very hot, may fry the amp (cut off if it has thermal protection), or melt the fuse.
