Fuel pump?
« on: March 02 2015, 04:40:03 PM »
What fuel pump do you guys recommend?  I'm going to be running 80's with Eric's chip using MAF and wideband O2 correction.  I currently have an XP pump, which wasn't sufficient when I bought it but Red wouldn't sell me his double pumper because he said I didn't need it. :rolleyes;   I was thinking of one of the 340 lph pumps.  What do you guys think?

I ran into a pressure problem going with a 340 pump. As in I couldn't turn the pressure down below 60 psi. Some guys got away with drilling out the Saginaw fittings and still running the stock lines.  I went with a -6 return line and a -8 feed.  Racetronix has a sender with the fittings already installed or you can do it yourself. I bought the sender and the lines secondhand from a member off the big board and I can't remember who sells the braided line.

A lot of broken parts does not make you a racer; it makes you a slow learner.

I want to be able to run around 20psi of boost on straight pump gas.  I do have alky but I want to factor of safety incase the alky fails, I know it will still get damaged but more can't make it any worse.  I'm putting out close to 500 rwhp with straight pump.  So I'd like to see how fast I can go first before turning on the alky.

A conventional 255 lph will handle 10.8.  With alky,  you can handle 10.0

For a bit more, you can go with the DW or the Denso.

I don't like double pumpers but you eliminate the return line problem.

Or, you can go with a 340 and do some replacing as mentioned

Is the Supra TT pump no longer the 'hot ticket'?

That is what I called the Denso pump...It's still probably the best quality pump out there...imo, at least :)  As you know, it is a little more of a pain to install because of the diameter but no big deal

I can't see a 255 supplying a enough pump gas for a 10.8 in a 4100lb car in a lighter one absolutely.  I am running mid to high 11's on pump with my 50's but they are maxed out.  Now that I have the 80's Eric said I don't have enough pump to supply them unless I'm on alky. 

I was also thinking a big single pump would be much simpler.

Jack at Racetronix sells the 340 LPH pump already installed in the SS hanger...it's plug-n-play. He also sells the larger supply/return line kit...which is also plug-n-play. He's located in Toronto...so shipping is easy. He usually has my stuff to me overnite.

Just checked Erics site...it appears he's no longer selling 80 lb injectors. Gonna order them from Jack.

Good point...    On the upside if forces one to inspect the hanger very closely and fix cold solder joints and fortify the fuel level rheostat.  :)
