I'm more interested in the intake.
Tuned exhaust is only worth a few ponys...but if you match the intake with the exhaust flow in the correct proportions.. then you talking. Nice work Bob. Are you using the 80 percent flow rate to intake? Last edited by wrench459; 05-12-2008 at 10:45 PM. |

On the bare head flow, I strive for 75-80% exhaust flow. Normally when the header is fitted, the exhaust flow will increase another 4-5 cfm. On this particular EFI intake, the manifold chokes the airflow by about 20 cfm over a bare port. Not great, but far better than the 'stock' carb'd intake that was previously used on this head (2.4). Usually the final numbers are closer to 90-95% exhaust flow once the manifolds are bolted in place. Here's the old thread where I tested a bare 2.4 intake port, a Dbilas DCOE intake manifold, and the 3.0 litre EFI intake manifold. HTH, Bob

Since you brought it up..
My guess is your going with a symmetric cam profile. Your thinking out of the box again Bob. Keep it up !! We might learn a thing or two. |

It's just the common everyday kind of craftsmanship you see all the time.
At Bob's shop, that is.

Very nice work Bob.......again! I've always admired your quality of work, but the part I like best about what you do is the innovation. It's always interesting to see your unique approach to ordinary tasks. Very inspiring.
Duane

Peak power previously on the dyno was @ 6500 rpms, peak torque I think was at 4800 rpms, but that was with a Holley 2-bbl. I think with the new intake and exhaust the peak hp/torque numbers will occur at a lower rpm. Bob

What plans do you have for the car? Any unique body or chassis mods?

Thank you, Bob! I've got a good start on the header, just isn't gonna get finished unless for some reason we want to race that car again. (Autocross has crossed my mind, by the way) And it is legal, just out of the ordinary compared to the competitors, yeah like the whole car is! They just aren't used to something being meticulously built in that class.

The body will stay as it is for now, but it's due for a restoration soon. I will not be involved with that aspect, I wanted to get it mechanically restored first. The one area I will modify related to the body is the front air dam and rear spoiler. The car needs to be stable, it will have enough power and rpms for 145-150 mph. So I have come up with a custom setup in my head, which I'll likely fabricate from sheetmetal. Bob
