He has 3 pulley sizes left to go on his current blower, and that's before he looks at different size crank pulleys, and several areas where he can still open up performance...if he wanted to hit 9's then VMP gen 3 all the way, that's a 1000hp+ blower, but for his goals the 2.3L TVS can hit 800hp and has pushed many mustangs into the single digits in the 1/4th. My recommended prescription is pretty much what I'm running, 72mm pulley, bigger injectors, and if more is needed a bigger throttle body. That right there is mid 11's all day long, but if still more is needed then a bigger pump with a BAP and E85.

Im not that up to date on the 2.3 setups, but my thinking is that after he drops a pulley or so his iat's will jump and it becomes diminishing returns.

The larger/more efficient blowers move more cool air at a lower blower speed and give more room on the current engine.

Also there are plenty of used vmp gen 2/gen 2r's that people will want to sell to upgrade to gen 3.

I sure you can get a head unit cheap as vmp doesn't pay much for trade in and its only good for some like @rojizostang

Just my thoughts

my buddy's 2.3 ford performance blower setup on e85 in his 14 mustang does high 9's, so yeah the blower is pretty stout.

He is still well within the efficiency range of the 2.3l TVS, and isn't even spinning it all that hard at 11psi with the 75m pulley. He's also got an ice tank he uses at the track, and 3...yes 3 heat exchangers on the truck. IAT's are not an issue for him lol, I looked at his setup and its way overkill but does a good job. If he was running a 63mm pulley with an overdrive crank pulley, I'd be concerned about IAT's, but not at a his relatively low boost level.

well I didn't start out to run 3 heat exchangers, it just kind of happened, lol. but at the track I don't use them at all, I bypass them. you can't run ice water through them without them forming a lot of condensation and dripping water everywhere.

really what I would like to know at this point (for future purposes) is if my current blower will match up with the gen II heads. I understand there are some differences with the intake ports, but I don't know if it's a deal breaker or not.

BadCon is right, I'm not really wanting to switch to another head unit...it's a $4k swap, sending them my old blower. A low mileage gen II to motor can be had at around $2600-2800 locally.

It might even be just as cheap (LOL) to just build the current motor with better rods and pistons, and then have perhaps some work done on the existing gen I heads, instead of starting out with a gen II motor and going from there. Space is also an issue as I don't really have room to store a standby motor anywhere.

Oh btw with the datalogging we did Friday, the highest ait2f's so far are 111 degrees. that was on the return road.

edit: with iats that low, and boost low, pulley down

Im not hip to the pulley sizes but if your only running low boost, I would start there and see what you can do.

If you have to get bigger injectors to run the smaller pulley, get ones big enough to run e85 even if you dont run it.

If you have it locally and you race your truck it would be the easest way to push your current motor to the limit, just pulley down...

that seems to be the consensus.

I suppose high or low boost is subjective, more or less. one person tells me 11lbs on a coyote is a lot of boost, another not so much. I think the starting compression ratio is 10.6, so it's not the same as a mustang motor where the compression is more to start with. when we went form the 80mm pulley to the 75, it basically picked up 1.5lbs of boost, iirc. going to the 72mm pulley would probably be only 1 more pound of boost, putting me in the 12lb range or just over.

so the next question would be, is that considered low, medium or high boost on a gen I f150 (with 10.6 compression to start with) ...relative to the stock compression and stock pistons and rods. Perhaps I should consider the 70mm pulley that BadChad referenced in his link in on of the earlier posts. that should put me around 12.5lbs of boost. Then of course belt slip may become an issue?

this might be apple and oranges, the 2015-17 whipple guys pretty much have to run a 3.500 pull to make good power (15psi)

the 2018+ guys have to keep it around 10-12 on 93 or knock is will cause a trade off (the power gained by added air is stolen by reduced timing)

don't the 2018 motors have like 12 to 1 compression? I can see why they would have to dial back the boost.

yes, 12:1 vs your 10.5:1

really it be come a head flow isssue, you will reach a point where power will fall if you try and stuff too much in.


call vmp and ask what the highest boost you can run is.

I won’t use them for tuning but they can tell you which one to get and sell it too you

ask about fuel also and get back on the dyno
