Ysi?
So i have a v3 ti trim blower right now and put down about 825rwhp car has run 9.74 in the qtr and consistently runs 9.8-9.9. I already have heads/cam/intake/meth on e50. Ive upgraded the hpfp and injectors as well. Im debating on either changing the pulley on my blower and doing lpfp so i can hopefully run straight e85 or saying screw e85 and running a ysi and c16.
As of now i hate screwing around trying to get my blend right with e85. Its kind of a nausance and never end up with the e50. Its always up or under. E50 which if its over i have to add more 93 since ill run out of fuel. Half the time i end up going to the track with almost a full tank cuz of playing with the blend.
So which direction would be best to go with? Both cost about the same. So cost isn't a deciding factor. With the ysi i will have more room to grow but my goals now are to be around 9.3-9.4 in the qtr. And would like some more torque as well.
Also going with the ysi would i need the lpfp? Or will i be fine as long as im not trying to run e85?
Thanks for any input

Go with the YSI and a 2.75 pulley that will spin it to the limit and over but the YSI loves it at that point. Will make its best rwhp & rwtq #.
But if the motor is all forged and good you will love even better the F1X blower. With a good set of heads & cam will put down over 1300 to the rear wheels.
One of the vendors in here say's it has all the pump and aftermarket fuel system these cars need for high H.P. Robert

Let me get this straight...
LT1 block, forged pistons and rods, cam, heads, and a YSI = 1300rwhp?
I do declare....
Could this be done with methanol and Lt4 injectors & hpfp? Or would secondary injectors and secondary in-tank pump be required?

yea. Nobody is making over 1000 wheel without a modified secondary fuel system.

LMR made a post a little while back of making 1400RWHP without a secondary fuel system.

any car making that kind of power has a upgraded secondary.

Car ran good like that but if I had the money and didn't have the YSI I would put a F1X head unit on the car. Due to on my c5 the f1x the boost come's on in the higher RPM range over the YSI, Plus I ran a bigger pulley on top with the f1x and with a 8 rib set up on the c5, Just loved the set up much better the way the car ran for me with the F1X.
I did go from a ysi 402 motor, To a 427 RHS set up with the F1X set up. Ran a smaller cam in the 427 but much better head set up from brain tooley head work and cam.

Not looking to go too crazy on hp. This is my daily 900ish will be more then fine for now. I walk to work but do have to do some city driving from time to time and over 1000 hp is probably too much for me right now.
I do have cam with 33% fuel lobe and lt4 injectors and hpfp with dual nozzle meth.
Will i have enough fuel when i go to ysi? That's my main concern.

What Pulley Combo are you running with the V3 Ti, is it currently maxxed out?

It really depends on how you are looking with fuel now, injector pulse, rail psi pressure, low side pressure. If you continue to run E85 you will run out of fuel for sure without upgrading corresponding fuel components.

With the ysi I wasn't planning to run any e85 if anything c16 for track duty. I'm just over the whole playing with the blend. I never get it to where I'd like it. I'm sure over time I'll get better at blending the fuel but I like the idea of the bigger blower, being able to stay a little cooler since I wouldn't be spinning it to its max and having more room to grow if I decide to.
