Default Anyone running twin 75mms?

I had a guy tell me he was running twin 75m turbos on an LQ9 based motor, topped with afr 225s, a fast 90/90 all on pump gas.

He claims 1400hp and 1500 ft/lbs.

Yall think hes BSing or is this viable.

Im not big into FI as Im poor so I figured Id ask you guys.

Maybe if he had a 511ci, better heads, better intake, 93 octane + meth and twin 74mm turbos from Borg Warner. haha

Basically he's lying his *** off.

And that definetly would require something more than just 93 octane right?
Are you talking crank or whp?

Oh and tiago have you been up in the DFW area in the last year, a while back I saw a red WS6 on cooper street and it had some pretty wheels that looked like yours and he hit and WOOOOOW, turbo spool and Boom he was gone. Me and my buddy were in amazement.

P.S. Cant wait to see what the car does at Goliad in March. I think you will rep the F-bpdy guys well and me and daniel will have some fodder for the local guys who say only Supras and Vipers are good for the 200+ club

Seems like nice round numbers so I am assuming he is just rounding everything off and UP LOL! Speed inc. Made the 1265rwhp on like 23lbs so I would guess he needs a solid 5+ lbs of boost to get near the number, assuming everything is relatively close in eff.

HP is almost always higher than torque in a gas engine. To make 1400hp with 1500ft lbs, the engine rpm would be just under 5000rpm.

^^^ This is true. Maybe he converted it to diesel!!

Though, my car makes more torque than HP but it's nitrous. . .
