So around how much HP you think i have to the flywheel and how much you think to the wheels??

Thanks In Advance

260-275 tops....to the wheels

 

ya, i'd say around 270-280hp. But for the size of that car (2750lbs.) ur really gonna be seein a lot of cars in the rear view mirror. lol

 

260-270 sounds feasible. But like the previous statement, you shouldn't have a problem stomping alot of cars..

 

What injectors and how much boost?

 

230rwhp

 

yeah what numbers you seein on that boost gauge? And install that SAFC-II and get it tuned and see you'll see a few more

 

240 rwhp

 

If you're lucky enough to not boost over ~12psi, then you should make a good 220-230rwhp (assuming you have cleaned stock injectors). If you're unlucky and make over ~12psi, you will make anything under 270rwhp for a little while before you blow your motor.

 

stock injectors and injectors where sent out to get cleaned and calibrated you guys really think i only have 230 to the wheels i was happy with people saying to 260 but anything else? any comments?

i have/will have almost the same setup .. i hope the 260hp estimation is close

 

5hp.

 

^^^????
TwEaK

 

I have almost the exact same setup on my S5 TII(see sig). About the same or a little more?

dyno it

lotta people seem to think its gonna be ~250 rwhp

only one way to find out...

 

230-250 at the wheels

 

At 85% injector duty cycle with stock 550cc's, you're only gonna have enough fuel to support around 260bhp (220-235rwhp). Any more than that and you are risking injector failure. So if I were you guys, I wouldn't "hope" for more than that.

 

I love when people say dyno it. Well trying to schedule a couple of dyno pulls in the MD/DC area is like finding a liver. They are all booked up with honda **** with exhaust pipes and air filters and the look on their faces when they 120front wheel horse is great. They all guess 200-210 and get half that.

 

lol you think then i should get the Denso 720 secondarys? Also ive noticed when i floor it hard and red line each shift when i let go of the gas black smoke comes out of the exhaust if im correct thats running to rich correct? Is there anything bad by getting that other then bad gas efficency?
TwEaK

 

I would very much doubt you are running rich with that setup. Do you have a boost gauge?

It would only mean you are running rich of black smoke comes out of your exhaust when you are on the gas, not when you let off. Black smoke coming out when you let off could mean oil getting through the turbo...
