Hey guys I recently brought a P1SC procharger for my A8 2SS.
MODS: Speed Engineering 1 7/8 Headers
DSX FF kit
Full 3" from headers (cats removed) to stock NPP Muffler
Lt2 Intake Manifold
Rotofab CAI.
I dynoed 380 on pump gas and 405 with E50

I want to achieve 650whp
I already ordered:
Snow Performance Water/Meth stage 2 Kit
LT4 injectors,HPFP and low side
I am contemplating to pulley down from the start to 3.5 and that should put me around 11psi with my mods and elevation.
Any inputs are appreciated.

Sounds like you’re on the right track. Get yourself a JMS voltage booster for the low side pump while you’re doing that in tank LT4 pump install too.

I am also thinking of a radium MPFST with dual Ti90000295.
The only thing that I am not clear about is how I am going to power the dual pumps, with this combo I am pretty sure I can also add a good chunk of E to the mix with the Meth.

You should really think about what your real goal is. You had said 650 WHP was the goal…if that’s the case the JMS and LT4 in-tank has you covered. If you think you’ll be wanting to really crank up the power, then skip that all and just do the Fore setup. But keep in mind that if you want to go much over 650 WHP I would suggest building the bottom end too…forged pistons/rods at a minimum.

Running E is almost mandatory with a SBE in my book…and still a no brainer at bigger power levels with a built motor. For example, back when I was making a bit less power, we did back to back dyno runs on 93 vs only E50. I went from 837 WHP on 93 to 906 WHP on E50 with absolutely no other changes. Same day, same dyno. The 906 run was hot too…97 degrees in the dyno cell…

The Fore double and triple kits are well thought out. For big power you want to do the return line (and might as well beef up the supply line while you’re at it), add a return style regulator, and it includes the multi pump controller too. The multi pump control pulls power off a big power line right off the battery in the back. At 4-5 psi of boost, my 2nd and 3rd pumps kick in automatically. Something to think about. I messed around with multiple low side setups before doing the Fore and I wish I had done it right out out the gate.

How many hours did your FORE triple take to install? I feel like my tuner who is some what used to installing them sounds to enthusiastic about installing it.

I am saying 650whp now but eventually I am going to want more, its the nature of the beast hahahaha.Probably sowhere between 850whp to 900whp.
I plan to build the engine eventually I just dont want to it at this moment.
And the thing is I want to upgrade the fuel system the right way. Its easy to try and bandaid the fuel problems on these cars and in the long haul you would have spend more money.
Can you elaborate more on how your setup triggers the 2nd and 3rd pump? I am interested

Hours? LOL. It took the better part of a week as we did extensive heat shielding of the lines, custom stainless brackets for everything, etc. All well worth the extra effort IMO. Gasoline is not something to half ass…

Sure, no problem. The setup uses a Hobbs switch to detect manifold pressure. It trips around 4-5 psi of boost, which activates the trigger for pumps 2 & 3 on the Fore pump controller.

Lol damn! I counted on it landning somewhere around $5500 installed. Like you said Fuel is not something you half ass.

The Fore triple is the ultimate low side upgrade. It pretty much future proofs your low side fuel system if you ever decide to go above 1000whp on E85.


Far as cheaper solutions that will work with majority of builds(<1000whp), There are now some bigger drop-in single pump options such as the Bosch "Big Boy" drop in that bridges the gap from the standard LT4 upgrade and full blown standalone systems like the Fore. https://smgspeed.com/product/smg-big...nd-gen3-cts-v/

There are also Aux pump kits if you do not mind tapping the tank. There are several vendors that sell these. DSX is popular along with SMG speed. https://smgspeed.com/product/smg-6th...x-fuel-system/

You could probably get it done for that. My installer is even more OCD than I am so we went a little more than that, but not too much more. You’re definitely in the ballpark.

Edit: make sure you get the pressure sensor setup to go on the filter so the car can continue to read low side fuel pressure. Also get the flex fuel sensor fittings since the sensor is too small to leave on the supply, and the fittings let you move it to the return line.

That new Big Boy pump is a great option too, good info King! Be a great choice for cars that want to make more power than a JMS can support without going crazy with the Fore setup. Keeps the factory bucket too so road course guys will love it.

If you go DSX or similar set up... a bulkhead fitting in the tank is more desirable than the tap fitting these vendors use, but if it doesn't leak then press on!

Yeah i have a room if he needs more time.

Thanks for the tips man! It helps alot
