3.5 DR750 build

[TurboSinceBirth]

I talked to Matt about this on the phone awhile ago and he thinks the stock intercoolers and exhaust he had was more of a restriction on his 3.5L DR-750 car than the motor itself. I thought it choked off the turbos but he thinks differently.

Todd, did you make the switch to a flashed ecu yet or are you going to run race gas for awhile with the ARC-2 until you make the switch?

Just the ARC for now. Dude has a spare 98 VR4 ECU in his basement and a BlackStealth PnP harness.... Keep trying to get him to do the change over.

i have yet to see a dyno chart that convinces me that 750's will not choke on a 3.5L engine. matt m's certainly didn't appear that way.

define 'choke'

[Chris@Rvengeperformance]

displacement aside peak horsepower will be the same and the powerband will be wider.

define 'choke'

based on HP vs. torque. the numbers on his pull (to my recollection) were indicative of the turbo gasping at higher rpm's.

why would you think that when horsepower is basically a function of airflow?

if i can find the original thread, i'll remember what the discussion was about.
