I'm just curious, are you still running 450+ ft lbs of torque at 4200 RPM, or have you retuned since that post?
Dan (drb) Just barely retuned it a little lower. But I ran it like that for three months with no side effects. |
Nice graph, that Ecu controlled boost is great. Ive been wanting to switch to that over my MBC for a while now.

safety over power in this situation. he wants the car to last. even a fp black without holding back tq would hurt the engine also. i usually hold back tq on every stock block car i tune unless told otherwise by the customer.. i always let the customer tell me what they want and go from there. if you compare the graphs you will see all i did was reduce boost at lower rpm and ramp it up as opposed to a mild spike. cool thing about ecu boost is you can mimic whatever boost situation you want. future adjustments will be raise the low end boost alittle more to flatten the curve to make the tq curve alittle more lined up flat then extract the remaining power out the top it has.. it should hit 530 without a problem based on the tuning it has on it now and the power it produced. |
Amazing looking car. Must be a blast to drive.

Tom & I will be running a BB Green on my car by the end of the winter, cant wait to have the perfect street beast.

maybe I missed it but are you running stock cams on your setup?

The car is out of fuel at this point, so I need to figure out what to do about a fuel pump / fuel system. If anyone has any idea's let me know. I would like to avoid the expense of a double pumper if possible.

Tom can really tune the crap out of these cars. can't wait to get tuned by him!
|
haha, I think all us hta green guys are out of fuel lol. I think I am gonna just go with some 1450s and a dw 300. Seems like the walbro 400 is either out of the question, or a lot of work to install in the evo 8/9 successfully. So I am gonna try the dw300, better than the 255, right? lol
|
Yea according to dave buschur the 400lph wont fit in the 8/9 tank. MAP's testing showed the dw301 was good for over 600whp, 33psi, 1500cc on e85 of course (2.3L 6262 test vehicle).
|
Yup, I think I am gonna give it a shot. I want to avoid the cost of the double pumper for now. :)
|
just get a dw 300 pump. i have one with 1450's and i'm no where near outta fuel on my hta green
