By 'stock' boost,do you mean 8 psi?
You would have to underdrive a whipple with a pully the size of a saucer to get it to only put out 8 psi..The new ones make 15 psi with a 3.5" upper.
A 3.5 upper is as large as you can physically bolt on a Whipple before you zing the hood blanket..I guess you could run a small lower...
If you were to run a stock OE tune with a whipple...It would not be pretty.
9A Pilot said:It's a little deceptive..What they mean by "stock" is a stock,factory tune Cobra vs a Whipple equipped Cobra with the stock-sized pully.The Whipples are shipped with 3.5" pullies,coincidentally the same diameter as the one Ford installed on the Eaton..
The power numbers are right on for a 15psi Whipple with no other mods besides the ones to make it work.
9A Pilot said:The numbers are probably for an older 13 psi unit...& the test car probably has stock exhaust & no CAI..Just the basics.At that level,even your stock injectors & MAF might work,but they'd be on the ragged edge,especially the MAF.They probably tuned the test car with minimal ignition timing also.
A new whipple,with normal bolt ons IS a 550 RWHP car at 15 psi..
