4.6 4 valves in FS weight

[L Reffett]

I dont understand why the 4.6 4 valve is at 3400 pds?

A 4.6 4 valve that I had made 341 rear wheels HP.
The 4.6 4 valve is required in factory stock trim to be in a 1994 or new body thus requiring a minuim of 53% in the rear weight for the chassis to work.
The 4.6 4 valve engine weights 155pd more that a 5.0 liter.
The 4.6 4 valve engine can not be set back in a car because of its physical size.
The 4.6 4 valve doesn't make enough torque to run a automatic


Why is the weight not equal to the 5.0?
This is why I am not running in Factory stock for 2003 season. You can not be competive at this weight!

I shall reserve comment until the "final" version of the rules are released. I've let my opinions be known to JL, Wesley, and Thom.

Miss Reffett, I heard that you were going to run in P/S with a 4V?

[L Reffett]

Yes, I'm going to run in pure street with my 4.6 4 valve. The weights are the same at 3150 for 4.6 4valve & a 5.0. You can put a 4.6 in a pre 93 model if you choose. The only diadvantage to a 4.6 to the 5.0 is that you can't take advantage of the knife edge crank rule, you don't have the MSD capablities of a ditital 7. The MSD 4 is nice, but it's still not a match for the ditital 7. In General there is still limited parts for the 4.6 4 valve.

[Tommy D]

Thats cool, our team is doing the same if our sponsorship pans out.

[L Reffett]

tommy d, If you want to do a 4.6 4 valve I could just sell you my car. I would much rather do a 5.0 in pure street, but I have to much invested in 4.6 to convert back to a 5.0.

Lisa...to answer your question....James Lawrence - and possibly others, I don't know - is afraid that at equal weights, a DOHC car would dominate the class. There is zero physical evidence to back this up, only unsupported speculation and conjecture. However, because of this, we must race at a signficantly higher weight - 200 lbs more in 2001, 150 lbs more in 2002, and looks like it will be 75 lbs more in 2003. If the trend continues, by 2005 we should be within 25 lbs of the fast cars.

Bob and Lisa,
At least you weren't "ruled out" of your class.

[L Reffett]

What class where You ruled out of & why?

[Thom Bates]

John,

I want to thank you for the letter I (we) received from you today, although the tone in the letter was not..... up beat.

You were not "ruled out" as you put it. You did state it correctly in your letter that the mod engine aftermarket has yet to catch up with the pushrod engines.

There is not the same type of camshaft development, nor is there a competitive cylinder head, nor are there cylinder block (cubic inches) advantages like there are with the pushrod engines.

However, we do extend the offer for mod cars to run in Hot Street at a ridiculously low minimun weight. Maybe it would be more appropriate for us to have no minimum weight seeing as how hard it will be (maybe impossible) to get there. We cannot intelligently make the pushrod cars come in a 3800-4000 lb minimum.

Don't take the rules personally, John. We want to have as many racers as possible, and you are included in that statement. Hopefully someday in the (near) future there will be good support and competitive aftermarket equipment that will force us to make you mod guys weigh more.

Hope to see you racing with us in 2003.

Tom,

We were not asking to make the big CI engines to weigh 3800-4000 #'s. What we were requesting was for more parity between the small ci engines to the big ci engines. We DID NOT ask for the weight break. You, as well James were informed at PRI last year by Keith Engling that there was NO WAY we could make the 2450 min. weight allowed to a modular. I was already at a bare minimum of 2740#'s with no balast and 54% of my weight on the nose. So, what does the NMRA do? Add another 100#'s to the modular weight break. That was the slap in the face that woke us up!

Now we are at a point of making a descision of what we are going to do for next year. Continue to run 9.50's maybe 40's, while the rest of the class is in the teens or better. I've had enough of knowing that there is only a slim chance of making it past the first round. So, when March rolls around our chances of being in H/S are pretty slim.

I wish the best of luck to anyone trying to play with a mod motor in H/S. Feel free to email me at michael@modularperformance.com and I can maybe help out in some ways.

Now take this statement, apply it to Factory Stock and doesn't it make you go hmmmmmmm???? :D

[Thom Bates]

Pulpdogs,

There is a huge difference between the engine combos in H/S and F/S. There is no comparison.
