robert why did you enlarge the manis? are they being modded as a top mount intercooler? how much longer is the v8 s/c compared to the v6?

I installed a 400LPH pump in tank, looped rail, and have the needs wings solution to your problem on the shelf.

your version of the looped rail wont work for most applications. you have removed the piurge valves to get enough room for the 90* fittings your using to fit. i tested a looped rail for ttm for 6 months and those fittings wont fit with the purge valves installed

I removed the the smog pump valves like 2 years ago. Again as we have already covered I have the LTH so no CATs to heat up with the air pump.

I made the setup even less flexible by adding a 45' to make the T on a 90' The plan is to run a -8 supply an relocate the FPR. I am still dropping to 45 PSI with all the fuel system upgrades.

Damn Ethanol

P.S. Save it about TTM and how cool of a beta tester you are. This is Roberts thread, I was just informing him of where the pressure regulator is located.

loudandheard

Are you doing a similar set up to Robert's? An E85 set up would be awesome, suppose to be affordable race gas.

I'm also curious as to way you enlarged the intake manifolds.

my post was to inform folks that might try your idea that it wont work with the purge valves in place. nothing more
get off your high horse. btw running an8 will drop your pressure even more but im sure you already know that

I didn't see where you installed the FPR, can you please explain more about your setup? is there another FPR in the tank?

i installed same as NW fpr but without success.

in the post nb 25 you can see the diff between the 2 sc in the picture attached.
no top mounts changed plan to water/meth. i am tired no more works.
i enlarged the manis coz i want more air/hp at top end and to lower torque and spin at low end.

The fuel filter is the Regulator, did you install the 124 filter or some aftermarket? The in tank pump is only 130LPH, I will PM you the pump I installed in tank.

My E85 Fueling issues are NOT solved YET

Jerry shut my car down on 2 dyno pulls in a row when he saw the AFR's start flying above 4K. Consulting the ZT2 (pair: L/R banks) the problem was clear, 45psi on the rail will not get the 550cc's enough fuel.

And yes E85 fill ups are very nice. I am currently paying 3.05/gal here in FL. Once the fuel delivery issues are solved I have no doubts people are going to notice the results of my 3.2L stock Blower vendetta.

I have had a 3.7L ML block waiting for me to make my goals a longgg time... I never would have fathomed to do Roberts inspirational blower swap. I paid close attention to the SCRAM build but I now think Roberts is more viable if I can source a higher performance HE.

i Know the filter is the regulator but i am asking if there is something similar in the tank, you worked in the tank, i didn't.
i took out the stock filter/regulator and installed an aftermarket regulator at the return line but i couldn't regulate the pressure, when i turned on the engine the gauge always go to max (>10bars), so i returned the stock filter/regulator and went back to stock pressure 4 bars with the bosch 044 pump, ev14 550cc injectors and looped fuel rail and now it's working good, yesterday i run the car and the afr is at 11/11.5 at high rpm, still with last C32 tune. i am waiting the 175mm pulley to arrive and install it then dyno tune with Jerry. all i can say now that with stock 55k pulley the car is spinning tires all third gear, the power is insane. the boost is at 1.4 bars (20-21psi) with stock pulley, with the 175mm i think i'll be at 1.6 bars (23-24psi).

Cool build! Let me know if I can be of any help!

Nice build... how far until completion? Post some vids please when you are done.

Somehow finishing, waiting dyno tune with Jerry, maybe this week, i installed today 175mm pulley. next week the meth kit will arrive. then 55K tranny and finally true dual exhaust.

what happened to this?

Wednesday is the date for dyno tune with Jerry, finally.
Last week my stock in tank fuel pump died.

Upgrade that pump and let's see some vids and numbers!!

i took out the stock assembly with the 2 pumps and installed a regular w203 fuel pump assembly with the bosch 044 pump instead of the regular pump with some cutting.
i thing tomorrow we'll be shocked with the nbs, she's a monster.

Yesterday was the dyno, my injectors(550cc) are maxed out, i need bigger injectors, it made huge torque but hp were low, i'll buy bigger injectors then we'll redyno. anyone has EV14 750cc injectors for sale?

racerxoffl

What do you have monitoring your true rail pressure? I have a ZT2 with a sender on the end of the rail I assume we are after very similar fuel needs. I need "30%" more for my E85 setup, your displacement/boost should be in the same zone...

my pressure droops off 12-14 PSI around 4k, this with the "400LPH" pump I had PM'ed you. I am not really sharing what I have done because with the masses because its not working and I don't want anyone trying it and blaming me...

Everyone keeps telling me to give up.

your getting a false reading the fuel pressure sensor mounted at the end of the rail. its like hitting a wall. the pressure reads higher than it really is. when i looped the rail the pressure dropped 2 psi and at wot the pressure went down another 5 psi . this was the true reading of the pressure in the rail
