Cowl rise hoods

[-=Jeff=-]

So this have been discussed before, I like the TP hood, but if there was one with less rise I would be all over it

There is a Guy on CF having a new one designed made.. here are pictures of the one he cut and modded..

What are everyone's thoughts? I have my opinion but curious on others

[Karl]

I am not a fan of high rise hoods, but I do like the lovers. But if I were to purchase one, I would want one not too high.

[-=Jeff=-]

the hood pictured also has about a 1" rise over stock on the cowl..

[Blue Flame Restorations]

Very similar to the Morrison Sankeskinner ZR-1's. The louvers are a little larger than the Morrison cars.

I like the 1" rise of the Morrison cars.

[Kevin]

like the slight rise, not interested in dumping water all over my engine every time i was it assuming those vents are functional. If they aren't functional, then I'm really not interested

[-=Jeff=-]

yeah I want the low rise.. not sure on the vents yet

[cvette98pacecar]

I Like it, If I only had a car to put it on.
Guess I will have to buy another car.

[GOLDCYLON]

Like the rise........ the vents/louvers not so much

[RICKYRJ1]

I'll take mine in black. I like the 1" rise and the vents

[Paul Workman]

I like the 1" rise and the louvers too, with reservations on the latter. As Kevin pointed out, I'd not be too wild about rain soaking the under hood. But, if that were addressed somehow, i.e, functional too, far as removing heat from under the hood, I'm all over it! Carbon fiber, by chance???:dancing If so, I'd be pulling out the checkbook!

[Bob Eyres]

Here's my "ideal' ZR-1 hood. I would love it if someone could knock off a mold from the active suspension car, (double click for close-up).
It's functional, but not too "boy racer" looking. The vents are functional, (on sides, not visible), are not to my liking. Possibly source functional vents from a '91-'94 Lumina (see below) with provisions for drainage.
Slight rise with a larger power bulge to clear the LT5, perfect.

[cvette98pacecar]

I can tell you from personal experience vents in the hood and rain. Not a good combination.

[XfireZ51]

One of the aspects of the C4 body style is rather pure. Its flowing and has very few interruptions or distractions. The hood is a large seamless expanse. The vents just "gunk it up" IMO.

[-=Jeff=-]

unless the vents are not open and functional.. It should be up to the buyer if they want them functional

[USAZR1]

I really liked the 2.75" taller Toledo Pro on my 90. It was well-made and fit was excellent.

Wouldn't recommend their 4" taller hood,though. Those are hard to see over.

[-=Jeff=-]

well the vents on this hood will be open..guess I will keep looking

Why does that TP hood look smaller then this TP hood?

It might be a 4" taller Toledo Pro.

[Bob Eyres]

I think it is a 4" rise. The bulge flows all the way down, nearly to the front lip of the hood. If I had that hood, I would have to have a 415 or twin turbo underneath it. It's like a rocker with a rolled up sock in his pants.

Clint's looks just right to me. But, I think from head on it might not be quite so subtle.
It's tough to improve on the efforts of GM styling. That's why I like the subtle bump of the Active suspension car, above.

I also think it's possible to have vents that have good water drainage. You see more cars today with vents in the hood than ever before. :dontknow:

[-=Jeff=-]

No that is not the 4" it is the TP 2.75" only only you can get.. Same as USAZR1

[Z Factor]

It has been a while, but the last time I spoke with the manufacturer about the TP hoods, they said that they were not making the 4" super high rise hood. However the standard high rise for our C4's have a 2 ¾” rise in the middle and have functional cowl induction.
They use to knock off $100 if you mentioned you were a member of our club if I recall correctly.

[FU]

The 2.75" TP hood is @ 40lbs lighter than our standard hood. Another good point is they vent (read limited) at back of the cowl.
I didn't care for the stand out look of the high rise hood. The low proflie sleeper look is what I personally like. Plus even the low rise T/P blocks some view for us short folk.
This is my experience , your opinion may vary.
Enjoy !

you sure it's only 40 lbs? I damn near ripped the hood off your white car the first time I opened it in BG in 2006. i couldn't believe how light it was.

[ghlkal]

I've been giving a Toldeo Pro hood some thought for a while now. I liked the 1" idea by the poster on CF, but I'm not sure about the louvers.

I thought the 2.75" was too tall, but in looking at Clint's Z, that looks nice!

Do you have any more pics?

hood does not look as big in this picture does it

[XfireZ51]

It would need to be more subtle for me. Bigger bulges and extensions etc. and the C4 loses its grace and clean lines. And that is the strength of the C4 design IMO, how clean, svelte and uncluttered it is. Anything that begins to make it look "Heavier" detracts from that.
It's visible in the side by side you see here.

[LGAFF]

Too much junk on the hood...non-functional junk...if it were one or ther other, ok...but NACA and vent..not for me anyway


how about this one?

http://i568.photobucket.com/albums/ss127/body-kits_dot_com/84_corvettetwinturbohood.jpg

[-=Jeff=-]

So it looks like if you want a Toledo Pro Hood you need to order by Wednesday this week as the molds have been sold..

Next Week you will have to buy from ACI.. Guess I will have to stick is Stock or maybe the first one posted. I like the one with the NACA Ducts, but I am concerned about fit and prep work required prior to paint..

I like the TP Hood, but too much $$ for me to spend right now, I was looking/hoping to do a hood and then have the rockers and hood painted but it just does not look like that will work out right now

[ghlkal]

Who owns this wicked Z? Someone in the FBI? I'd love to see this in person (after it warms up next May ;))

[8cam]

What's the point? I'm genuinely curious because it seems like an anachronism when looking at something like a modern fuel-injected quad-cam engine. In the old carb days, cowl induction could be used (fairly easily) to guide air to the carb by taking advantage of a high pressure area. But to do that with a ZR-1 you would have to completely redesign the intake, reversing it and going with something completely new. If not actual cowl induction, I could see it making room for a high rise manifold or a supercharger, but then you're talking serious money. If the goal is weight savings, surely someone could fabricate a lighter stock-profile hood (carbon fiber anyone?).

Then again if it's appearance only....well that's kinda like putting Kate Upton in a pair of overalls. Still sexy but kinda wtf?

[-=Jeff=-]

What's the point?

Because I am in need of a hood.. I have don e other things to the car to make it my own, this was potential as one of them..

I have done BFR Rockers, Prowler M1.. why? because I liked the looks

I will probably end up with an OEM hood, but I like the first one is a 1" bulge, that just sets it apart from the rest, subtle enough to not be obvious at first glance

So out of all the hoods, I would choose the one I first posted.. I am not too big a fan of the vents so I am on the fence regarding it, but I need to wait for it to release

weight reduction and improved underhood heat removal, plus it looks cool.

seems like enough points to me

[8cam]

I can definitely appreciate making it your own, go for it! Lord knows I've done a lot of stuff to my own cars over the years. I just always pictured cowl induction hoods on big muscle cars designed to run the 1/4 mile, not sports cars capable of shaming Europe's best. I guess what draws me to the C4 are the clean elegant lines, and this seems to disrupt that.

It does look cool though. :D

[BigJohn]

My throttle body used to rub on the underside of my stock hood.

How about this from Greenwood? I got it from Ecklers.

[Kevin]

haven't seen that hood in a while.

[GOLDCYLON]

With that rear spoiler it looks very Trans Am esque... However Frank approved lol

[-=Jeff=-]

Tony is that piece a bolt on from greenwood? I actually need a replacement hood but I could always add that scoop now if I absolutely wanted to

[-=Jeff=-]

Tony,

i like that Greenwood scoop, but I could get a replacement OEM hood for that (used of course)

[RICKYRJ1]

for the guys who don't like the vents or ducts on the hoods posted maybe filling them in might be an option. I understand it is an added expense but you'll be closer to what you want. Modifications to the modification we with the bug do all the time ;)

[RICKYRJ1]

how about this one?

http://i568.photobucket.com/albums/ss127/body-kits_dot_com/84_corvettetwinturbohood.jpg

Try to envision this hood without the NACA ducts, I think it would look good with the nice rise :proud:

[-=Jeff=-]

Or all black and it will somewhat hide the NACA ducts

[RICKYRJ1]

Or all black and it will somewhat hide the NACA ducts
I agree that would help also

[Blue Flame Restorations]

One of the Snake Skinner race car hoods has a low rise approx. 1" hood also with the vents. It looks really good, IMO.

The vents could actually be made to be functional and have a water trough for directional drainage away from the beautiful LT5 power plant..

[-=Jeff=-]

So if/when I swap I have narrowed it to the hood with NACA or the 1st hood ( last resort will be OEM)

[Tony Davila]

Tony is that piece a bolt on from greenwood? I actually need a replacement hood but I could always add that scoop now if I absolutely wanted to

Yes, it is bolt on and fits really good. Had to cut opening in hood. Almost wish I had a clear insert.

For those interested in hood louvers. The ones that come off a Pontiac GTP work awesome and fit.

Back side of hood with opening cut. Had to figure out something because I dropped my hood down with the radiator cap sitting on reservoir and it cracked the underside of the hood. These louvers fixed my problem.

Hey Tony,

I don't but will take some tomorrow for you and post them.

[Tony Davila]

Hey Tony,

Jeff here are some pics of the underside with the louvers. They fit perfect and if you use the drip rails the water drains onto the top of the tire cover. You only need to drill some small holes to allow water to escape from the top of the tire covers.

4 bolts and your choice of urethane adhesive. I did modify the scoops up front which was the majority of the work.

Wow, that looks great. I'm surprised no one has done the clear insert on a C4 ZR-1 hood yet, especially since the LT5 is an incredibly beautiful engine. The C6 ZR1 hood certainly doesn't look that good, just looking at the flat top of that blower.
The only problem would be if the top of the LT5 is offset from the body centerline. I can't tell from your shot Tony, the angle might be slightly off. Is it right down the middle?

[Tony Davila]

Greenwood scoop fitment was very good. I just prefit to hood just to make sure then had it painted then it was bolted and glued to hood.

Hey -=Jeff=-,

We have similar tastes as I also have the BFR rockers (not installed) and Prowler M1. As you know I bought a used TP hood and will install the Greenwood louvers and replace hood latches with Aerocatch system. The only bummer is I won't do this until I get back to Hawaii next year and will post all the photos when I do. Best wishes in finding a hood that meets your tastes and I was just fortunate to get a good deal on a used one locally in Hawaii otherwise I would not have one.
