Walbro's are usually around 400-420rwhp. ND is usually 430-450rwhp. The answer is yes, I can tune it to the limit of your fuel pressure. I can easily tell by the inj time map so we can go as much as your fuel pump allows you. Just a reminder, you'll need to run race fuel on anything over 16psi since you guys run 91 octane....

^ Pluto - I have 850/1300's with a Nismo Skyline R34 (275/280lh) fuel pump. How many lbs of boost would that max out to? I can get 106oct race fuel. Would the HKS ignition thing make a big difference? Would I be able to max at 475-500 rear wheel ponies?

I may end up going, but my car is currently in the shop getting rebuilt (and a bunch of other goodies). Is anyone with stock twins (seq/non-seq) going? Steve, what do guys with stock twins/fuel/ignition/IC usually get power wise? You can assume 91 octane fuel and boost around the 10-14 psi range... TIA

EDIT: My car is non-sequential. Any info is appreicated.

Spoke with Dynamic Autosports again. They said $100/hr and this time they didn't want to waive the $50 hookup fee per car. Their dyno is loaded. New equipment, large building, lots of empty paking spaces. I left them my number so if they want to match RR&R's cost they will let me know but I doubt it.

Guys, for all of those who said they were interested and are planning to get a tune, I need you guys to sign up at the www.rotaryx.com website. The way to sign up is to select the bid button for $350 (the cost of the tune). All details about the tune is at the following thread.

I don't know about the Nismo skyline pump but I know that the Apexi R34 pump is good to around 550rwhp. if you plan to run more than 14psi, you'll need an ignition amp. There's no reason to go cheap on the ignition system when you have already spent so much on the rest....

as far as the hp goal, that all depends on your car and how it reacts with your turbo combination along with the rest of the components. I don't see why it is not possible to get it. What single do you have? GT35R? I think they'll max out at around 450-500rwhp....

pluto

depending upon the condition and efficiency of your compoents, I would say anywhere from 280-310rwhp.

The Nismo R34 pump should be the same thing as the Apexi R34 but what about my 850/1300's, is that the weakest link? ...anyhow, I don't think it will do more then 500rwhp @ 15lbs on 91oct.

Ok, I will order the HKS twin power then.

I have the GT35RS/500R (devided) T4 short runner manifold

i just want 350 rwhp, with my mods in my sig that isnt asking much lol...i'll have the jacob's fc1000 installed and hopefully new wires and a FC coil woot!

i just want it to run smooth and be semi-reliable...you know what i mean. (priority smooth operation not max power) the whole reason i'm lookin for you to tune this is because you tune reliable and power together...and my car is running stupid rich right now

350 with stock wheels and tires is more than enuf to spinnem thru 3rd gear...i do it now with 300

RX7_Fanatic

i dont understand why people want to tune their street car with race fuel...its going to be driven a lot and you want to simulate as close as possible what you would normally do on a constant basis...i for one couldnt afford 106oct in my daily driver =p

^ Why to guys want to see what is the max they can bench? ...it's only one rep and they won't do it every day? It would be a seperate tune just for bragging rights mostly but the maps would be there for track days. My friend has a barrel in his garage. His roadster is about 1000hp and gets about 1mpg "lol" but it sounds like a thunderstorm and he has electron wheelie bars. He needs a ZZtop beard. Chicks dig it though.

...Steve said up there that we need race gas for ppl tuning over 16psi.... now since I have a walbro pump and am lookin for 400-420 at wheels. do I need race gas for that? from what i thought i read was that 400whp is about 15psi depending on setup yes. I'm thinking that ill need a little bit just to be safe. but lookin for second opinion.

mods are T04s(hotside)T04x2(intakeside) pettit street port. 800cc-1600cc injs.

RX7_Fanatic

what boost do you think i would be running to attain 350 rwhp on a stock ported engine with t04e xs kit

p.s. to steve...have you had any experience tuning cars equiped with the jacobs fc1000 ignition amp?

ImranRX-7

I have a deposit with XS for tuning, but I'm willing to retract it if Steve Kan is coming to LA. Gardena is like 10 mins away. Let me know if it's for sure.

.... i'm pretty sure its for sure.... did only read the first page then post?
