The new "Showstopper" hood has significant clearance over a stock hood. The heat distortion temp (HDT) of our resin is fairly high and more than adequate for any temps in the US but we could build a hood for you with an even higher HDT

Here is a link to the "Showstopper" hood,

The old cowl inductions for street cars like a '70 Chevelle were to let air in the engine intake, but they still sealed off the back of the hood. Race cars open up the back of the cowl, but they have no HVAC inlet.

There is a reason the ZL1 has the hood opening up front, and the back is sealed.
Drove it in the summer, in 100+ degree heat w/o any problems and a 1000+ hp engine. And only on the hottest days do I even have to run the AC so I guess I am just lucky. Actually my stock 2012 corvette interior gets hotter than my Camaro does and it's hood is completely sealed.

I'd be putting an f1 or f2 procharger or vortech ysi before I'd go whipple.
I dont know what you know about Whipples, FYI the 4.0 has the ability to flow 2500CFM+ which is how much an F2 Procharger will flow, so I will actually be on the low side of the compressor efficiency while im on pump gas.

are you talking about inlet temps while cruising around or inlet temps at WOT? and do you have proof to backup your statement?

Im asking because ive owned almost everything, centri Z06, TT Z06, ZR1, TVS2300 427 truck, Whipple 2.9 camaro.

I also have all the options for me to choose from and I choose the 4.0

No seriously, so when you're driving with the AC on, do you have any issues? I know what Russel's saying makes sense, I just dont know if it will have any real life issue with the intense summers we have.

He may not have proof, but I do. I log IATs with my Aerforce Gauge, and I am constantly at 2-4 degrees above ambient with my Vortech.

Good for you for owning everything. If you are buying the 4.0 Whipple just to say you have it, then go ahead. If you want to do it the right way, there are much better options.

The A/C will still cool it. Where you notice the extra heat is in vent mode with the A/C off such as on a cool day. With the hood sealed, you will be able to get cool ambient outside temp vent air. Take the rear seal off, and the vent air is quite warm when the vehicle is not moving. It will feel like the heat is on, instead of just cool outside air.

The easiest way to see the difference is on a stock Camaro, taking the rear hood seal on and off to compare. When you can A-B-A test the change, the added heat to the HVAC system is quite obvious in vent mode when sitting in traffic. In A/C mode you will still be cooling OK, but some like to use vent mode when it is cool out.

I live in Houston so humidity, not temp is the real issue (yes when you combine the two it sucks). Low humidity and 100 degrees, no problem, no AC. High humidity and 100 degrees, I turn on the AC.

First when you have a large, high hp supercharged engine heat will always be an issue. If I am sitting in stop and go for long periods of time, my temps will run up but they are still manageable (usually 225F max). Of course my engine holds about 11 quarts of oil and I have two oil coolers.

Unfortunately people make comments about things when they don't know the whole situation. That's why half the time I won't even post anything on here because someone will always make an uniformed comment.

A true old school (70's style) cowl hood would release heat low and into the vents, however the MPD1 hood is not the same. It seals at the back and the holes are high in the cowl, plus this cowl is significatly higher the any normal cowl so the air that escapes is way too high to be sucked into any vents. Unless of course you live somewhere that hot air sinks and cold air rises. If that's the case then this hood will not work for you.

Well if you want to go oldschool you could always go bigger and cut a hole in the hood. Good luck with your build.

so you're saying Whipple's are a bad way of making power? or would all Positive Displacement blowers be a really bad way of making power since Whipple's are the most efficient of the bunch?

Now when we talk about IAT's no one cares what your intake air temps are while cruising around, show us how they look like when you step on it.

Vortech's are awesome dont get me wrong, my vortech z06 was insanely quick. Centrifugals also work really good on higher compression motors, and especially stock motors because they boost by RPM, so you only see full boost at redline.

PD blowers put alot of stress on the engine but make an insane amount of low-end torque, and would probably be in full boost at around 3500rpms. 800rwtq does feel nice at 3000rpms.

Also, this is a no expense spared build, were using the biggest heatexchanger, high flowing intercooler pump, large intercooler fluid reservoir tank etc...

A bunch of tuners tried dialing this monster in and none of them were able to, until they sent Mike from New Era Performance to New Orleans to tune her, took a while but it worked out!

Hes also the tuner for the fastest COPO in the country #003

Well it looks like Procharger may have just solved that issue for you... They are showing there new i-1 at SEMA. It will have a built in transmission which will allow for the pulley size to change while driving. I do not know the numbers as they have not been released, but if this is an option available on their F1's I am confident it will be hard to match it.

Anyways, back on the subject, if you have the cabability of fabricating something for the firewall then can't you also do some fabricating on the stock ZL1 hood to make it fit your needs?

As far as I understood, you can switch boost levels, which means run 6psi, then turn it to 12 etc...? Its like a turbo with a boost controller.

I dont think its going to smoothly gradually transition from 6psi to 12psi to make both low-end and top-end.

I wish I could take some material off the ZL1 hood to make it fit, we will have to find out but I doubt it will fit, that blower is HUGE.

Firewall will be worked on and/or the supercharger snout, so I guess ill have to wait and find out really.

It is going to make a smooth transition, that's the same way that boost controllers and wastegates make turbos run. I would be looking at this more than the headache from running a whipple 4.0.

In that case it will be awesome, id still want to see it out and tested before I put it on my engine, not sure how durable the variable gearing system is and if its prone to failure etc... I really dont want to be the guinea pig on such a new technology.

Worst case scenario for me is i slap on a COPO hood, the guys at the shop have alot figured out regarding the modifications to the firewall and so on after working with a COPO camaro.

the wow factor, torque, upgradeability, efficiency and more are still leaning towards the 4.0, its done deal dont try to talk me out of it

I might post a build thread, just not sure yet. I might post it on ls1tech or something, but for anyone interested follow new era performance's page on facebook, the updates will all be there.

Im doing so much PR work for new era, hell they have to pay me for this lol.
