• Whipple with H/C, SPI, low side, Meth, E85, Cut Hood
• Eforce with H/C, SPI, low side, E85, 30-45% Injectors, High Vol Fuel Pump and a New Hood.. maybe meth needed?
• Maggie with H/C, low side, E85, 30-45% Injectors, and High Vol Fuel Pump... maybe meth needed?
  (I would go Maggie - no questions asked - if I could do SPI and not need meth)

Or, Procharger and SPI <- however that's $10K+ for the blower kit.

Port Injection for the Magnum DI TVS2650R will be available as an add on.
It will fit a Camaro, not a Corvette - I'll post more details as they become available.

Looking forward to the cfm airflow chart comparison of the Magnuson and Edelbrock 2650 with port injection in the mix.

The supercharger performance won't be any different than what has already been provided. Its a positive displacement device - the CFM of the device is controlled by the inlet conditions of the supercharger rotors.

Is this the hotrod model that was installed on Guitarmageddon's ZL1? Or is the 2650R that you installed on your C7 capable of supporting port injection? I'm only curious, because I'm not understanding the logic of adding a stand-alone fuel system, now, when there are DI systems capable of doing the same thing, for near the same price, using OEM PCM-control and such, but to each their own. I'm just curious over the comparison/interest from others.

standalone lets you inject meth which has a large tolerance for max rich HP, basically, you can pour the stuff into the engine and it is more like a steam engine as some of the increase in HP is in part due to the expansion on the liquid (aka steam engine), more total joule content, and lastly more phase-change cooling. So at this range, you can never do as well with just DI. I went to DI just because on a pure street engine, I felt it was a more dependable, simpler and turn-key setup. But a race car or 3/4 race car... dual inject with meth is very advantageous.

The 30% injectors and Lingenfelter pump are nowhere close to keeping up with these blowers on E85. Katech has 45% injectors and a belt driven fuel pump but it’s considerably higher than port injection. Port also keeps the valves clean. PFI supports everything these blowers can make on E85 without any meth. If you choose to go the Holley route you have full control of the throttle body, spark timing, and the ABS sensor for traction control. It’s using dual widebands for quicker, more precise adjustments. I am no tuner but I would guess it has to be easier and more versatile than tuning the finicky factory ecm as well. It’s not for everyone for sure. There would certainly be other hurdles to cross using that much power, like belt slip on the 8-rib, and having a drivetrain that can handle that much power but it’s gonna be necessary at some point. After seeing and hearing cfm flow numbers I have to assume it’s gonna take a serious fuel system to keep up with these blowers. Seems like a lot of the Procharger guys have gone the port route on big power. It’s a link in the chain when you are chasing big numbers. No doubt we will see some crazy builds ahead. You can also see how the ZR1 has benefited from PFI with its track times. I haven’t seen anything close to that time on direct injection alone. It’s a fun thing to dream about anyway. Affording all that it is laughable though

I can assure you with cam lobe the above will support just about any HP that anybody here is running on a street car. So you might want to retract that. The OP is talking about a street blower. I have no opinion on what a race car needs, as I have always contended that any race car needs cubic $$$$ period, plus it is completely off-topic, to what this guy is tossing on an otherwise stock engine. Once again 30% injectors, pump and lobe will have enough HP to BLOW UP ANY STREET ENGINE PERIOD.

Thank you both for the insight

In Oklahoma they often close the road and have street races. I am not talking about anything illegal here. The towns agree to do it. You show up with only 30% injectors on E85 and your gonna be dead last and probably laughed at by everyone there that spent half as much. I wouldn’t recommend it. You better add some nitrous into the mix. You will never hang with late model Coyotes or lightweight nitrous big blocks. There is a place for the extreme.

[ramairroughneck]

My best friend is building a forged, ‘18 3.0 Whipple GT with fuel upgrades. It’s a tough thing to be competitive with what he is spending. It’s gonna take a lot of extra on my side to even be close to his car. My post chronicle the extreme but I think it will take ever bit of that.

The eForce build that is well documented on the ZL1 sub forum has FIC 30%, Pump, Cam, heads, etc.. and it's still not breaking 'safe' engine levels...

If I was limited on budget, I rather add the secondary port injection and be done with it, it is actually a much easier job IMO than a cam swap, can be cheaper, and it is easily reversible.

Looking only at cost:

Port Injection Kits (lets go expensive & pick WeaponX)= $5K

Or

PUMP, Injectors, Cam = $6250 - $6750

• FIC30% = $3500 or XDI45% = $4000
• Big bore pump Lingenfelter= $1750
• Cam Kit (TSP)= $1000

Also, port injection as mentioned before is great for adding meth to minimize heat soak.

Everything has pros and cons, I prefer to have it all: get a cam and port injection.

And Edfhobbbies has maxed out that system already and pullied back to slow the blower back down. Besides the fueling, I want the traction control as much as I want anything else. It has to be better than the factory tcs.
