If you call them, ask for Bruce.

 

just remind me GG - did you have any success when you went the 550cc INJ? I thik nyou did.
I would have thought you guys would be angling more toward the 750's based up on a n 80% dutyc
I do however recall the pulse width control quality and everything else was scruitinised in this thread.

Did you go for Wood's dynamic reg or just a stock constant 5 or 8bar reg.?
Ring'd fuel rail manifold as well?

sorry - just too lazy to re-read....

The injectors worked perfectly at correcting the lean condition. Take a look at my signature for more info on the subject.

- 181 pulley - Lean issue fixed with SL55 fuel pump. Trap speed in the 1/4 increased by 5MPH as a result.
- Stacked setup - Lean condition fixed by adding looped TTM fuel rail and injectors. Already had the SL55 pump installed from the previous lean condition.

In both instances above, that's all that was done. No changes to regulators, no solenoids added, just what I posted above.

 

Thanks for the info. I was also on MBWORLD site and Bruce PM'd me about the rail, injector setup but haven't gotten a price as yet. He did assure me that it would cure a lean cindition caused by 181 pulleys and up along with the SL55 pump

 

Get the SL55 pump from Rob at Needswings before you do anything else. Might sound stupid but no reason to do looped rail if you aren't on the cusp of needing it and I know this pulley with Robs intakes only needs the S55 pump and Rob has the best price on it. You can always get the rail in the future if you add mods and need it.

 

Thanks very much. That is exactly what I am going to do. I don't track my car, I'm more into the GT car experience, high performance touring, so the SL55 pump sounds like it will get me where I want to be.
