Because the snout on the stock supercharger isn't large enough to utilize it unless you get the supercharger ported.

ok so is there that much of a difference between mamo v2 and 95 in order to justify buying a 95 to replace v2?

I don't know I am not the one that suggested it. I do know I would of went with a ported 95mm before I spent money on a ported 87.

^^^ This unless the goal was to leave the car basically stock.

ok so a question I never really could find an answer to:

even with upgraded tb mamo or 95, is the factory tune going to compensate for the air by closing blade more, making it useless after initial install and ecu calibrating? is the only way to see true benefits of this a tune??

Virtually every mod you do will need a tune. Period.

Your rotor pack needs to be fed more air if you want to make more power. A ported 87 only belongs on an NA bolt-on SS, not a modded ZL1. GM found it necessary to make the upgrade to the 95mm TB for only 755 crank HP, so I think you can see where this is going…

So what you are saying is that 87mm is the wrong part for the car? I find that funny considering GM and Tony Mamo both specifically use these specs. The goal was to increase throttle response while throwing a little more air into anticipated increase in fuel. I wanted to maximize the money spent on tuning and bolt on what I could. In hind sight I would have ported the supercharger and snout then added a NW 103mm. However, with that being said you also begin to walk the tightrope of fuel system and heat exchanger upgrades. Also, the R&D from Tony Mamo on both TB (V2/LT5) show about the same increase in HP/TQ. Actually the V2 is higher by 1HP if you want to get into the weeds. My point is that there was no overwhelming proof that the 95mm would benefit the motor anymore than the V2 for this application except for this exact reason a TB measuring contest ��

I do not see SS anywhere in this product description

Do you seriously believe that swapping your ported 87 onto that ZR1 would make the same power as it did with the ported 95? Because you seem to be claiming the 87 is better by 1hp, come on man, use your head.

I agree with joshinator99, the 95 could be a better choice than an 87 on your tuned car, if it fits properly of course. IF the stock ZL1 blower opening allows a 95 without using a restrictor plate, then it's a superior choice than an 87 for hp on a tuned car. However, if you must use a restrictor plate (because the stock blower opening is too small) to mount a 95, then don't bother in that case. Restrictor plate defeats the purpose of the larger throttle. Bolt pattern is a different issue that can be solved 2 ways, either slotting the bolt holes of the 95, or using an adapter plate. Some 'adapter plate' versions though are actually restrictors, and I've seen one version that was not a restrictor, so it's important to research them carefully before buying.

Like I mentioned above the goal for this application was simply to remove the off-idle flat spot as well as gain a little better throttle response. Ported TB seem to be a very controversial topic in multiple forums. I have not been able to drive it yet so I honestly cannot tell you if it did either of those. I felt it was not beneficial to add a 95mm to a stock snout that would require a $200 adapter just to close back down to 85mm again. The parts added were merely to open the car up a little until I can do the full build at Vengeance again. I love the information on the forum and discussions like this just fuel my appetite for more knowledge on every front. Thank You Guys

So you did a 17% lower pulley and dyno tested it with Boostane to “remove the off-idle flat spot”…?!? I like how you think if so.

They make a slotted 95mm ported TB for like $399. If you clean up a little tiny amount of the inlet opening at the bottom with a carbide burr, it will clear the 95mm blade easily. I did it back when I still had my stock blower. Feeding the rotor pack is extremely important to the efficiency of the rotor pack, regardless of your power level. I have a 112mm on my 2650R. My friend just upgraded from 112mm on his 2650R to one of the 120mm Nick Williams beta test units (not out yet officially) and went from 1040rwhp to 1069rwhp in back to back pulls. The 112mm is huge already and can be fisted like Jenna Jameson, but still can leave power on the table with a PD blower.

As for Tony recommending it, that’s like asking Pfizer if you should take their vaccine. GM went from 650 to 755 and felt the TB was a restriction. Thus, the 95mm was born. You can hit 755 crank on a stock LT4 without trying hard. I did 682 rwhp on e40 with a pulley, CAI, and a shitty tuner.

If you changed your lower, it is pretty much certain that your car is already pulling power. I’m surprised you don’t have an air flow correlation code. I got one just changing my CAI. Any time you come closer to 100 ft lbs of the torque limit, the PCM will sprinkle in something to kick your power back down. The closer you get to the target max, the more it does.
