Motordyne helps with the detune?

It should not make as much peak power as the stock one but might help to flatten the curve.

Speculation or proven with dynos?

Specuroven.

That's what I'm getting from it, as it seems like the M370 manifold loses top end (but gains mid-range), at least on all of the dyno charts I have seen.

^ What he said. Generally on NA cars the M370 helps flatten the curve a little. More low end, less top end. There have been lots of charts on this for un-tuned, stock cars. I think the big question that's been hanging in the air forever is whether the M370 does anything at all if you're going to dyno-tune with UpRev, as the gains from tuning and the M370 seem to overlap on NA.

Also, Travis may be the first to document trying it out with a supercharger, so it's all new territory.

I have the Motordyne and TT.

I never did a dyno with and without the m370 but I have never seen any set of dynos to prove what the M370 does with FI.

Good question, gents.

Not sure if we will be able to dyno with the stock and M370 because I have the stock piece with me 3 hours away from car... but that's the theory we're going on... yes, in NA, M370 = *slightly* flatter curve, which I think it pretty well documented in Tony's thread...

I'm wondering if there's something I can do with the exhaust as well to flatten out the power delivery

My gut-level instinct would be to downsize your exhaust flow a bit to match the desired peak. In general that seems to be the directionality of these things. Within reason, an oversized exhaust will give peak gains and cut low-end torque, and an undersized one should do the opposite.

IIRC you are running a single-exit... you could play around with an H crossover ahead of where both your pipes collect into the single. Sort of like a NASCAR short-track setup where they are trying to maximize low-mid range power.

It has taken 2 evenings but I read this whole thread. Great work. While reading there were several people mentioning warped rotors. Have a look at the attached article. I have had "warped rotors" and fixed them with a power drill and wire brush on both surfaces just cleaning the friction material off. Its alot cheaper than the $400 rotors I was replacing at the time.

^thanks man! always appreciate when folks take the time to read 100+ pages of this!

So, nothing to report on the car.... wish I had some news! will let jason comment when he can

Somewhat unrelated... finally decided that the Ford was too big to be a DD and tow vehicle and got the bug to upgrade... here's the new ride (actual pic)

... any of you guys have recommendations on Tundra mods?

SPOHN · 01-07-2012, 10:05 PM

Tundra is good to go as is. Or you could gut it and race it also. Lol.

Yup. That's the impression I've got from reading Tundra forums... exhaust doesn't get you any hp gain. Maybe a few from CAI and tune but not much.
