Bah... Inner fenderwells just add weight!

Beware of aftermarket TH400 crossmembers, many that I've heard of over the few years have to be reworked to fit right (center mount). They are making them reproduction now, the same crossmember works for the 68-74 Nova as the 1st Gen Camaros. Maybe by now they have them fixed. Nothing serious but I had to cut the mount off of mine and reweld it about 1/2" over to one side. Dang Chinese don't know how to read a tape measure I guess.

Go to your GM dealer for the crossmember they can still get them I got one for a 68 Camaro a few months back.We never run inner fenders but have read some thing on turbulance with out them so on my Dad's car we got a set of fiberglass ones from glasstek and they fit nicely but his is a street car mostly.I am thinking about ordering some for my nova. What do you think about the turbulance thing John?

Damn, I thought I was the only one who got one of those miss welded crossmembers. I bought it direct from gm(chevy dealer) and it too was off, I thought I was seeing things. I just cut the mount off and moved it over also.

I would only be guessing on the turbulance thing, I have no measurements to prove pro/con either way but I do like having those fenderwells out of the way. It would be an interesting thing to learn more about. Anyone have a wind tunnel we can borrow???

Actually saw a show on I think American Muscle or something like that where they did that Project Nova (the black, tubbed 69) and it had no fenderwells. They took it to the strip to test and for some reason it was always leaning out and laying over at the top of the track.

Some big influencial person was there to help them test it and he found the problem right away. The turbulance under the hood was actually robbing the air from the carb and causing the fuel to do strange things. At high mph he said it can pull the fuel right out the top of the carb.

They put a air pan on to seeal it to the cowl hood and the car went like a mad man down the 1320. They also fabbed up some semi-fenderwells as well as the air pan to help with turbulance.

...just my two bits :)

I've seen cars running 169 mph with no inner fenderwells without a 'leanout" issue. I don't really buy into that Project Nova excuse. Not that what they did didn't fix a problem, but I don't think you can generically say all cars with no fenderwells are going to see a problem like that. If that was the case, every Nova and Camaro you see at the races would be running them.

They are supposed to help with the Aerodynamics of the car at high speed

ProStockers run them even with the one piece frontends.

I am with you John on not having them in the way.I don't seem to have any problem from not having them but I am wanting to try a set of fiberglass ones and a air pan.I was also reading in Carcraft about putting somthing behind the grill and this guys nova always picked up a 2 mph.I am just wanting to play with this and see if any of it helps.Jason

Ya, I saw the same show not long ago. It was Hot Rod Television, the person who found the probllem was Roy Hill at his drag school. He does make a good point, without the fenderwells they said with the turbulance at the top end I has a tendency to pull fuel from the bowls and lean the motor out.

Is that only suppose to be a problem with cars that have a Cowl Hood and no fender wells??? Or any type of hood?

Thanks

Artis Houston uses a piece of plexiglass to cover his grill on his Nova. It was good for a few more mph.

I would say the fuel control problem would be with cars that have a scoop with no pan to seal it to the hood or more factory set ups.If you have your carbs above the hood this would probably not be as much of a problem.

Do you guys run air cleaners and do you think a air filter would help with stablizing the air? I have been going to try running with out.I have been running a 5-6" tall filter with a K&N filter top wich gets up in the cowl hood.
