A second?
Heck, I'm working on tenths. I don't think I'd ever get this car into the 12's without a swap to a T-56.

I ran across these dyno comparisons for my Cobra. Not exactly what I remembered earlier. Looks like - 5 RWHP around 4K and up to + 35 RWHP over 6K.
The first shows the addition of JBA short headers and the IMRC deletes. At that point I already had an X-Pipe and U/D Pulleys installed.
The second is after the addition of a short runner lower.

I only have the 2nd comparison with the TQ #'s.Do you by chance have the corresponding RWTQ numbers?

I finished a cobra intake swap on my Mark. Sorry it's taken so long to post, much thanks to DLF, Stromberg, and all others who have posted valuable information on this thread. The intake itself looks way better than the old which was in rough shape inside and out,(it was a northern car for 5 or 6 winters). I also fixed the oil leak on the bottom of the timing chain cover, which requires the removal of the valve covers, so I decided to go ahead and powdercoat them as well as the crossover tube. I wish I would've powdercoated the alternator and power steering pump reservoir brackets while I was at it, but oh well, they're easy enough to remove and get taken care of over a couple of days off work.
The vacuum line issue proved more difficult than what I thought originally. I couldn't find a used IAC line, (from the IAC valve to the intake tube) for less than $80. For a used one, What a rip off. I bought a hose long enough not to kink that runs along top of the radiator. I think it's a little ghetto, but after about 300 miles, the hose still seems to be in tact and in good shape so maybe it will work in the long run? Let me know what you guys think.
As far as performance goes, over the stock intake: Way more throttle response. In fact my wife almost ran into the mail box her first time behind the wheel after the swap, lol. And don't get her wrong she drives a brand new Charger R/T with a Hemi, so she's no stranger to performance.

That'll work
, but now you need to introduce yourself in the new user introduction forum. We'd like to hear about your car and see more pics.

That vacuum line was specific to the Cobras so I hear ya there. I think I got mine for a bit cheaper than $80 off of a Mustang forum. But regardless, you're right. It is a hard to find piece and generally, people want a lot of money for them. You're not the first person to use a standard hose for that application though. It will work that way and you shouldn't have any problems. I can also relate very well to the performance aspect. The Gen2 intake manifold is horrible. I was running low 14s with bolt-ons and stock intake. After the swap, my current best sits at a 13.59, over a half-second quicker. That was on a mail order tune. The car has been dynoed now and has a low 13 in it. DLF is currently the fastest all motor Gen2 Mark VIII with his setup. There's something to be said there about the Cobra intake swap. I believe every Gen2 Mark VIII should have one. The intake design on the 97/98 models from the 93-96 models took a royal dump.

I can't speak for the gen 1 intakes from experience, as I've never driven one. The difference from gen 2 to cobra intake is certainly worth cost and labor IMO. I've read on the forums that the gen 1 intakes are better than gen 2's. In fact, the guy I bought my gen 2 from, also owned a gen 1, and admitted that the gen 1 was faster/more responsive. In any case, I believe I've got the best of three intakes available for the B-head.

Dlf are you going to be offering parts for this swap?

Throttle cables,vacumn lines. Egr eliminated. Everything a non master fabricator would need to makethis plug and play intake swap. Thanks ken

Not likely.
As there are too many different ways to do the swap, I think it will always be a custom undertaking. Unlike many, I chose to retain all of the emissions equipment, and that adds some parts, deletes others, and changes the vacuum hose routing. Then there are the issues of the IMRC's (retain vs. delete), intake tubing, and tuning.
Also, the early Cobra throttle and cruise cables are obsolete, so newer, more available cables would need to be used. That requires custom brackets, that I didn't need, and have no inclination to design and build.
Sorry.
