^ 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?

TRD supercharger? Can't have the Z be the only supercharged car in the household...

haha! that's truly the last thing on my list right now... I'm hoping 400+ torque will be enough... but if we're all still here posting in a couple years, you never know!

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.

couldn't help myself... these afe parts are on the way!

49-46008 - Cat-Back Exhaust System
51-81172 - Cold Air Intake System
46-38005 - Throttle Body Spacer

Pretty consistent +35-40 lb-ft result, from what I've been able to find

^ Damnit travis hahaha

Soo...what happened with the car?

I'm sorry that I was the one who recommended him and got you into this mess.

travisjb · 01-11-2012, 10:34 AM

hey Raul

...there is some catastrophic failure we are dealing with... I'm not going to get into specifics yet, until we verify exactly what is going on and decide how to resolve... needless to say, I'm twiddling my thumbs and anxious to get my car and myself back on the track
