I'm wanting to put a YSI on my LS2 and make around 690-750whp. I would like to know what pulley you all think would be best and if you think I should look into running a restrictor plate. I'm trying to lay down the ground work for a 800-1000whp build on E85/E90. (Don't worry I don't think 750WHP will last long on the stock block, I already have a spare block, once I get done with this go around I'll starting ordering stuff to build that block. )


This go around of mods will include. (I have everything but the YSI)
Switching to E85/E90.
V7-YSI.
1300cc/123lbs injectors.
Full custom fuel set up /RSI triple hat/RSI rails.
Twin DeatschWerks 300LPH fuel pump.
Ported Fast LSXR 102.


Mods I have already on the car, right now the car is making 615/530 on 91 octane.
A&A kit V3-SI-Trim at 8psi
Thunder Racing Track Cam. (Will change to a FI cam later on)
Patriot Extreme Dual Valve Springs Titanium retainers.
Comp Cams Pushrods.
Ported TB.
Dynotech LT Headers with gutted Cats
Corsa Sport Exhaust.

You should be able to lay down 700rwhp with a 3.33 pulley and a reasonable tune. I have one laying around in 8-rib if you'd like to try it. Send me a PM

I know you didn't ask, but:
1300cc injectors aren't nearly enough to make 1000rwhp, so I recommend you consider a set of 2200cc by injector dynamics (can be purchased at Dallas Performance)
I would also recommend you add a 10-rib serpentine system for good measure.
The FAST 102 is nice, but not necessary to make 1K RWHP.

Thanks for the offer, I will be sure to let you know if I do need the pulley.

I do have to ask if you are sure 1300cc injectors are to small for 1000wheel? Only reason I ask is because I got my Injectors all ready, and I told the shop I wanted 1000wheel hp on E85. They told me 1300cc would do around 1,300 wheel at 43PSI @ A 80% duty cycle. When on E85 you give up about 30% of everything which should put me around 924wheel, Then I would just up my base fuel pressure to 55psi and that should give me 1043 still at a 80% duty cycle.

All my math is with
Brake Specific Fuel Consumption of .6
Max Duty Cycle of 80%

I come up with the same stuff, unless I'm missing something, I just want to make sure, before I return anything/go back to this place, to tell them the injectors won't do what they told me they will do, and they need to take them back.


Thanks for any input into this.

Anyone have anymore input?

Why do you feel the need wait to blow up your current motor to build a better one. IMO you should just rebuild your current block for FI and sell the other block or keep it just in case. Not worth the risk of damaging your heads.

HumanVette

I'm not trying to blow up my motor now, I just want to lay down the ground work, for when I build my other block. Once I get done with this go around, I'm going to send out my other block/heads to build it. IE, in the next month or two.



I'm not a fan of breaking in a new motor/fuel setup/tune all at once. Been their done that, if something is wrong it is hard to pinpoint what is causing it.

I want to get my fuel setup done, and a good tune. That way once I get the new motor I can break it in, and if something goes wrong I know it is in the motor not on any other parts. Also I believe doing it this way will keep my car from having a lot of downtime.

AtomicLS3

Now that you explain it more I understand. I thought you were trying to just keep boosting the motor until it eventually gave out to have an excuse to build a new motor. Don't know how I came up with that one

This car should be pretty stupid when it's done! I'll see you on the playground homie

You can make that power with a T-Trim.

i just installed a 3.25 pulley on my Si trim and i bet im making 700 whp.

my setup

elminator pump
hob fuel system
e85
id1000's
ls9 head gaskets
arp head studs.

13# boost.

haven't dyno'd yet, but i was at 630 whp on 9#.

ive taken it to the track and now im hitting the rev limiter way before going across the traps, time for some taller tires.

p.s. i am at 76% injector duty cycle base psi of 58 with a referenced vac/boost regulator.

No, thats what im doing.

^ Please tell me the car is tuned??

I think 1300's will be enough injector for now and in the future on E85. Now Jerry if you get crazy and try to do 1200whp like someone else might be doing this winter lol, you will definitely have to go buy yourself another set of injectors. But if the fuel pressure needs to be raised near stock to get more out of the injectors the pumps will be able to handle the load I'm pretty sure.

HumanVette

A T-Trim will support 800-1000whp?

0EG@EnglandGreen

No, I was answering his initial statement about 690-750 wheel horsepower. I didn't read the rest of the thread when I replied
