maybe a lil twist and comment on the Stealth Ram as well. I have a modified MR I that I'm planning on swapping when I put in my new engine (deciding between MR II and SR)

isn't this on a sticky?

Super ram pros"
emmissions okay
works well with shorter dur cams (driveability)
best for auto's
tuned for good tq and hp balance
properly matched SR/cam/head/ci will have more (and available earlier) rpm range available

sr woes
250 CFM flow will limit hp performance
nightmare to work on

MR pro
400+ cfm max hp potential
easy to maintain
will actually tune at 5000-5500

MR woe
emmissions
performas best under big duration cams
better with sticks
slightly more expen$ive than SR (for no reason!)

you'll always want that extra 1K rpm when shifting

MR pro
400+ cfm max's engine hp potential
easy to maintain/work on
will actually tune at 5000-5500
happy power is 2000 and up

MR woe
emmissions
performas best under big duration cams
better with sticks
needs gears to be happy (3.45 plus)
slightly more expen$ive than SR (for no reason!)
happy power is 2000 and up

The SR will actually work quite well with longer duration cams. In fact it will actually be a better choice with a larger cam because of its longer runner and its large volume plenum which counter acts the reversion process from a large cam. With a "shoe box" style intake like the MR and the LTx manifolds, reversion makes tuning in the low RPM cruise regions a nightmare with long duration cams, this is especially true with stick cars which result with more felt cam surge. With an A4 car a loose converter absorbs most of what would be felt in a stick car.

The SR base and runners can be ported to flow considerably more, there are many SR equpped 350 and 383 C4s out there that are running well into the 11's and with only a mild 219 cam. Where as the SR will have a broad power band the MR is more peaky and will pull a bit more on the top end, therefore allowing the use of larger cams to take advantage of the longer power band. But one fact is true and that is that they are a bi**h to work on.

I originally used a MR, then took it off and put a SR on.

If you want to feel TQ driving around town up to @ 4500rpm, then the SR is for you.

If you want to feel a major pull at @ 4500 and up then the MR is for you.

I like the MR but it was no fun unless I was all out accelerating on the interstate or exit ramp etc.

The MR had tuning issues at idle, the SR was tuned much much better in 2-3 tries,

At the track the best my car went with the MR was 12.5, no slicks at 115MPH.

With the SR, I cant say for sure yet becasue my clutch is slipping and I actaully lost ET going 12.9, but my MPH was still 115-mph.

I would say that when my clutch is fixed, that my ET will drop down faster than the best of 12.5 and all in all, the SR will be an improvement.

My cam is in my sig

just my .02

With your setup you should be running at least a full second quicker in the 1/4 mile.

Maybe with drag radials - he is doing d@mn good on street tires.
He has got to be spinning off the line.

Correct, my best 60' times were 2.1 seconds, I believe. If I could hook up I would say it could mid 11's maybe lower
