Alright I know I have seen it but after an hour of searching I am just going to make this thread. What all do you need to run E-85 on the lsj? I already have the areomotive pump and 80's what else do I need? return style?

 

It all depends on your mods. If you list your mods it will help get you a better answer.

 

In the process of a build but as of right now:
Diamond pistons & rings
darton sleeves
k1 rods
zzp longtube header
stage 2 cams
p&p head
neutral balance shafts
82# Valve springs
ati ud pulley
aeromotive fuel pump
s2 front mount heat ex
phenolic spacer
opt b.
dual pass
3 inch intake
vibrant exhaust
and right now the m62 with a 2.8 but currently looking for a deal on a tvs with 2.9

oh and like I said 80's as far as injectors go

 

Im running 60s on e85 with almost the same mods.
I recomend a stock fuel pump works well the aeromotive isnt set up to handle the corrosiveness of the e85.

 

I am trying to get as close to 400 if not over 400 as I can will the stock pump support that?

 

Hmm good question...im not sure maybe some one will chime in im at somewhere around 340 on e85 with stock fuel pump. Ive done a few mods since my last dyno 330whp

 

You won't make 400whp with that build on a 2.9" pulley on the TVS. Realistically, your looking around 350-360whp with a fuel system setup that can support your mods.

On the stock fuel system, your car will probably make ~330whp before maxing the setup.

With a Return Style Fuel system and the stock pump you will make between 340-350whp before maxing out the pump. That is where I am at with a stock longblock and 2.7" pulley on the TVS. I am running about 70psi of FP at WOT and my IDC hits 100% around 7200rpms. I have not tried bumping the FP yet but I would like to get the IDC into the low 90s at WOT. I am pretty sure the stock pump is near its wall.

If you want to make more then ~350whp with 80s you will need a RSFS and a high flowing pump.

Get OTTP's Return style system with the DW300 Fuel pump.

Return Style Fuel System For LSJ

It is a very well put together kit and worth every single penny.

That fuel system setup should be able to support almost 400whp.

With your build and a 2.7" pulley on the TVS, you could realistically make 370-400whp with a really good tune. Breaking 400whp is going to be very difficult without increasing your displacement. But you have the right build to get close.

 

Those numbers are with E right? And would adding water or meth injection help anything?

 

Awesome I appreciate it man. I knew it would be hard as hell to make 400 without changing the displacement but I figured I could get damn close

 

Yes. Just E85 and they are all approximate. Differences in dyno and tunes can make a big difference on the final numbers.

Guys with ported head have seen between 360-380whp. I personally have not seen any dyno results from a 2.0L TVS cars with ported head and cams. A lot of guys are running them but they are scare of the dyno or something...

I have seen one ZZP 2.4L stroker with ported head and stage 2 cams break 400whp but I can't find the thread at the moment. I am not talking about Turbo Tim's Stroker Redline.

 

I have area tuning the car so I know the tune will be on the money its all on the build. Is there anything else you guys would add ?

 

Im buildin a 2.4 stroker lsj right now..hopin to be around 350-375 with the m62 on e85 then higher than that with a tvs

 

you might want to dump the 80's and get 1000's

i have a redline of 7k with a tvs and 2.7
running 80's return style and a dw300
and my idc's are 85% with a max fuel pressure of 75psi and a base of 50psi

 

where can i get a set of 1000s? I have never seen anything over 80s

Thank you anyone else got any thing else I should throw on in hopes of hitting 400 or more?

 

Some water injection would hurt. It will help keep the charged air temps down.

 

Would it really make a difference while running e-85?

 

The lower the charged air temps the better.

 

Just water injection with e85 on a 7 gph jet i saw a 5* drop in iat2
Not worth it
My iat2's hit 135 at the end of a hard pull back to back
Which at 25 psi isn't too bad

 

Would a bit of windshield washer help then? Not for tuning, only getting those iat2 temps lower

 

Really. I would like to see the before and after logs to check differences in Ambiant air temps, IAT1s ect...

 

5* really isnt worth the effort

 

5* is hard to believe...

 

5* was was with a 7 gph nozzle

which at 25psi isnt enough

imo i needed a bigger jet or a small mix of meth in there

but i see no reason because i rarely see anything over 140* iat2
