Richness Performance & Nitrous Questions
Ok... my friend is looking @ another friend of mine's car. I've just learned of an odd setup that I have questions about. Here's the setup.
S4 6-Port, Stage 1 SP, Ported intake, TB mod, Removed 5/6th sleeves, Bonez race-pipe, and a dynomax cat-back.
For his fuel system, he has 460cc Primarys, and 720cc Secondaries. On TOP of that, he has a TII Fuel Pump, and Pressure Regulator. No fuel control system at all.
Wouldn't he be better off with the stock 460cc's, and the TII Fuel Pump (N/A Regulator)? He should be running so unbelieveably rich right now.
My suggestion to my friend wanting to buy it would be 460cc's all the way around, N/A Reg, TII pump, and S-AFC.
What is anyone elses thoughts?
Lastly... when running a wet kit or Nitrous; don't you just have to make sure your fuel-pump can handle pumping the extra gas to the soliniods & injectors? You don't have to upgrade injectors for wet kits.... right?
Thanks ~Colby

Running nitrous on this set-up... Keep the TII fuel pump, get an aftermarket fuel pressure regulator, ditch the secondaries and revert to stock 460's. Even running just the TII pump with the stock regulator (TII and N/A regulators are identical internally) will make you run rich at idle and low throttles, as the flow is too much for the stock regulator, hence the resistor pack in TII's.
Flow test the system with a known gauge before using the nitrous system.

I'm not 100% but i think the extra fuel (wet kit) plumbs in with the nitrous (each on thair own soliniods) though a jet Type nozale. The stock fuel pump N/A or not is ****. You may be able run the 720's if you are going to use a S-AFC. Just reduceing 720 dutty cycle. They are running at only 80% dutty without the S-AFC so with a 50% decrese to play with you should get the flow rate your looking for. Thats if you whant to save cash on injectors and going to run the S-AFC.
hope i could help.
