Hey guys i recently got my S tuned at 8.5 psi and made 340whp and 231tq on a gt2871R, Any boosted S2K's making numbers close to this at those psi levels?

 

pics of your graph... love to see how that GT28 did up top......

but at 8.5psi those are good #'s in my book as long as timing and fuel are on track..

 

very good numbers. stock compression? I'd like to see the graph as well if you can.

^^I agree.

 

Good numbers, but throw up a graph when you get it.

 

Ok cool yeah i'l throw up the graph here ASAP. It kept going upwards all the way til 9K but we ended up running out of injector, they were pretty much maxed out so we turned the rev limit down to 8K so it wouldn't lean out.

I should have the graph up in a few minutes.

 

WHAT INJECTORS??? GOT A FPR?

 

Those are really good numbers, thats over 100hp over stock to the wheels on 8lbs. Be happy those are great numbers

 

Right now we have 550CC and someone told me that the injector driver in the EMS is not as powerful as the stock ECU driver, so i guess even though it reads like 90% duty cyle it could really be at like 75% or something like that.

I don't have an aftermarket FPR just the stock one.

 

Wow great numbers.... whats the graph look like.

 

I'm waiting for my tuner to get back from lunch so he can e-mail it to me.

it will be up shortly no worries.

i guess its my turn...

WOW!!! really good numbers... LOL

 

haha thanks guys i appreciate the support.

Casey is almost done eating so once he's done i'll have him send the graph, these Lotus' take up ALOT of his time. lol

Thats not true about the ems. The duty cycle value it displays is simply calculated from the length of the programmed fuel pulse compared to the time to complete a cycle at that rpm. I'd pick up some bigger injectors or bump the fuel pressure (youll need a retune of course).

 

I actually already have the 750cc and a walbro fuel pump and a 3-bar map sensor.

I know i will need a re-tune, but thanks for the advice on that and the EMS, like i said, someone told me that so i wasn't sure.

 

have it partial throttle tune alots, it's easy to do one position tune but it takes some talent to tune a street car that can be civilized and have power that can be used at the same time.

the peak number looks good, but peak number is just peak number, torque and power band is more interesting and useable than just a number.

 

graph?

 

it's not just a dyno queen, it spools almost instantly and is GREAT on the street. BTW i just picked up my AP2 diff with 4.77 gears

Please keep flamin to a minimal as these are the first 3 runs to get the car running.

Once the 750's are in and VTEC is engaged at 4300 along with 4.77 gears, this thing will rip up the streets.

Please keep in mind this is NOT the final tune at these power levels

looks like that turbo is still breathin nicely up top. Is this stock compression? what manifold?

 

Yeah this is stock compression on a full-race manifold.

 

ahhhhh you got 4.77 gears... plan on doing exactly that... ripping up streets and not moving anywheres... traction will be a huge issue... i would have recomended the 4.56 or the 4.44's depending on how much HP you plan on going. not trying to be a dick or anything but id rather see u use the HP/Torque that you achieved from the turbo instead of using tires constantly...

Good numbers as well...

 

I got them for a REALLY good price complete with AP2 diff and pumpkin assembly for $500 and since i work at a shop changing them out shouldn't be that difficult (within reason) and labor and tools are free, fluids i'll have to pay for lol.

I beleive you on the traction part, but hopefully with a fully tuned suspension and better tires, i can bring the traction loss to a minimal, but i do know traction will be an issue. hehe

well you could always just sell me the pumpkin... im lookin at buying them ASAP so let me know... that way you can just get the desired setup... even with proper suspension i feel like u will be losing traction too easily

 

This car is amazing on the street

 

haha i'd rather find out for myself first rather than sell it and never know lol.

If i end up not liking the gear i will most likely sell it in the same condition it's in now.(only gonna take a couple pulls to see how it feels)

I'm pretty good at keeping the hard launches at zero since i know AP diffs are the weak link.

I'll let you guys know how it goes.
