Mod Man intake.

Nice looking set-up. I was thinking they looked like the old Rat Roaster intakes for the Hemi.

I would realy like to see if they are any good at delivering more HP ! So far they look like to big in the plenum and short runners and there have been alot of those done in the past for multipel carbs as Edelbrocks STR intake for an exampel that whas a total disaster when more then one carbs whas on the lid if the one´s that say they tryed are corekt

I put one on my hemi 2 years ago and took off the Vanke modded factory intake. I also went from the factory carbs to a pair of new eddy 750's. I picked up .3 in the 1/4. I don't know if that was the carbs, the intake, or the combo, but probably a little of both. My 60 foot didn't change, but had traction problems with the new setup. Then a few passes later I dropped a valve and haven't been back since. $$$$. I'm sure if I could have resolved my traction problems, my 60 foot would have come down and I would have picked up more overall. So, in short, I was happy with the upgrade, but once again, it was an upgrade from the factory intake and carbs.

Were either set of carbs tuned for the combo? Most guys that have factory carbs have never once changed a jet in them, and a calibration from the 1960's does not work on today's fuels so I am curious because .3 is a big jump. What ET did it run before and with what mph, and what did it change to? MPH is Hp directly...

---

Yes, the original carbs were tuned to the combo. Lots of test and tunes on those old carbs!! .. It ran consistant mid 11.20's @ 122mph. Put the modman and 750's on, and listened to advice from some old-timers on the initial jetting, and went straight to 10.97 @ 125mph. That's without any major test/tune because I dropped a valve, and well, it still sits in the garage apart. Hopefully this summer I'll be out again. As always, $$$$....

Cool, so the carbs weren't that bad. I would say it works then. We have had our eye on the Modman intake, but have not had a chance to try one yet. I have run just about every other intake there is on a Hemi, and after seeing the above mentioned Vanke intake and seeing what the FAST guys do to them, I am pretty sure they work well. Even on the small blocks they got a very good write up with them.

Was the dropped valve because of an over rev at all? Been there done that....Sorry to see that.

---

I don't believe I over revved it, but ya never know. My rev limiter should have jumped in if I got too high, but again, ya never know. I haven't even tested the spring yet to see if it's weak. That's my guess of what caused it. I was so disgusted, I just parked it, tore it down, and have been slowly picking away at it. Once again... $$$$.... I'll be doing the heads soon so I'll test the springs then and that should give me a better idea of what may have happened. The valve actually broke when the engine was cold, on initial startup upon arriving at the track. There is a distinct line on the stem where it can be seen that the stem had cracked, then broke. It just didn't snap off in one clean break...if that description makes any sense. So who knows
