    PROJECT: "HARDCORE ACR-700R" Has Begun

    Yes, I'm aware of that. Just looking to hear more metrics/data for the gen4 heads & cam with mopar controller. Any wideband A/F data for part & full throttle verify how good the mopar controller responds to a modified gen4 motor? Was a A/F gauge installed on the car? And what about...

    question about boost compression ect....

    I'll keep it real simple for you. with a 700hp crank motor and 10 cylinders thats 70hp/cylinder. Hp can be written in terms of force as Hp = Work/time Hp = Force*distance/time Hp = Pressure*Area*distance/time Area of piston, distance & time (rpm) remain constant. Therefore Hp...

    question about boost compression ect....

    Well for any particular motor from a hp perspective increasing the volume of air going into a cylinder via efficient flow and increasing compression ratio slightly or solely increasing the air pressure into a cylinder via forced induction has the same effect of increasing hp. If I can recall...

    650rwhp...super responsive

    I think I may have misquoted the 9.1qt I used 10 qt oil with the new filter and I thought that was a bit high as measured by the dipstick. I think the dipstick fluctuates 0.5-1.0 qt high bar to low bar. Been monitoring the oil level allot and it has been holding very stable. I thought 10.5...

    Supertuned Gen 4 Viper beats ZR1 and 599 Ferrari

    These results are as expected. The ZR1 needs a tune...The 599 really lights up right outta the factory. Good to see with little modification ACR gets much faster.

    Part Throttle issues

    A new TPS was installed at time of built motor about 8 months ago and it was set properly. I'm not sure if it's the TB but my car does buck a bit. I like that seems normal. I've had other cars that did that a bit too.

    Part Throttle issues

    Dyno Day

    You should just get more data...only way to know... everythings relative and measurements scales are easily & often shifted. Searching & quantifying data for good benchmark helps us stabilize expectations. Have your tuner show you other cars dyno numbers on his dyno, or find dyno numbers of...

    Dyno Day

    Its not appropriate to assume this until you know more about your tuners dyno. Is the dyno generally "high" or "low". Typically a dynos most valuable test is before and after gains from modifications...there not all calibrated to be identical....4% between dynos for 600rwhp is 25rwhp...

    Dyno Day

    You may want to ask your tuner for further interpetation of those numbers. Gen4 with headers, exhaust and Mopar controller dont make numbers that high.
