Mthis goes to the dyno!
Mthis im sure will explain the mods and the exact numbers but ill give a general idea.
But he made a best of 450WHP today, with 2 carpet fans pushing up front... The fan/air situation wasnt ideal and he could have made a GOOD amount of more power with better cooling and air up front but that will have to wait for a next time.
I am guessing with proper cooling and better fans, about 470WHP+ honestly.
Mods off the top of my head are,
MHP ECU/TCU...MHP headers, no cats prim or sec....... Stock exhaust with stock mufflers and no sec cats..... BMC drop in filter..... 180*F thermostat.
Outside the dyno shop, lady cop in altima pulls over lady in altima.
1st run of the day, with the single carpet fan as seen in the above pic, fan in yellow, pointing at the bottom of the bumper.
2nd run of the day with a little cool down and adding a second carpet fan same as the other but now pointing up towards the engine from the bottom, which realisticallwas probably hitting the front radiator. LOOK AT WHAT EXTRA AIR DOES! C63 LOVES AIR.
3rd run, same 2 fans pushing, wish we had another fan setup towards the engine/intake.

I tough they, the cops, were coming to get you because of excessive noise.
I agree altima drivers can be crazy sometimes, unlike law abidind C63 owners
way to go on those numbers

I'm sure he can make more power than that. I had full Kleeman K2, Evosport Intakes boxes and BMC filters...Dyno'd in at 415hp and 400tq.
I would think with the MHP headers/tune he would have some more.

Hey guys, it was a dynojet, that may be reading a little low... his first run he ran a 390WHP with a single fan as you can see in the picture, yellow carpet fan. We let the car cool down and added a second fan pointing towards the airbox and ran 445WHP because of a cool down and a extra fan!!!!!
So if we had another fan and another cool down run, im sure he would have been up there! His car is jus amazing, each run it was juss throwing higher and higher dyno numbers. He is going to the dyno again within the next 2 weeks, so we are going to make sure the fans are proper and the cool down is 100%.
+1 for the track rather than the dyno, but mthis rana 11.8 @ 119mph with bald street tires in 400DA on a track that is borderline slow!!! And he spun first into 2nd during the run, so his car is freakin moving!!! I am amzed by it.

Nice numbers but it seems odd I've seen this fan excuse on here lately without supporting info. What did the weather station read that is suppose to be in the dyno bay? It will tell you all the details like temps, humidity, etc. It looks like it was up North looking at the pics so it couldnt be that HOT. If you were in South Florida during the summer when its 110* then the fan excuse is legit. Dont get wrapped up in a dyno # anyways. They all read different and its the before and after that matters. My race car had the lowest reading numbers but has every World Record possible. Anyways, congrats on the nice numbers.

Ok I ganna try this one more time. But shorter this time.
Mods.
MHP Tune
MHP Headers
BMC filter
180F T-Stat
1st run was made with one fan pointed to the bottom of bumper. Car made 390rw sae and 380tq.
2nd run he added another fan and pointed up to the hood to cool the intake NOT direct to airbox the air was hitting the top of motor. Car made 439rw after 10 min of cool down.
3rd run same fan setup more cool time(20min) but still no fans to the airbox car made 445rw sae.
NOTE. This is not the Dyno I used when I did my baseline (375rw sae stock 5th gear) and (421rw sae 5th gear with a tune)
As soon as I get some free time I will go to the shop I used to do basline I will go. And hopefully tonight Ill post up graphs of the results.
P:s I also dynoed on Dyno dynamic tue morning and dynoed 437rw and 455rwtq. Yes my tq numbrs were higher 3 times in a row. Ill post does up when I get a chance.

That is simply sum amazing numbers he put down and ran. BTW Brisk335 how much is your car putting down to the wheels, if you did dyno your car in the past.

Should heading out there next week to this same dyno.. On pump somewhere around 350-360WHP... depedning on the day. (dynojet)
Going to try with some vp ms109 race gas (105 octane) see what my car will put down with 15psi or so
hoping close to 400whp . (Stock FMIC, Intake piping, Downpipes, secondary cats) Basically a tune with intake at the moment lol..
On topic:
Its interesting to see what some good air up front will do for power on the C63. 5th gear is going 190mph, so with 30mph or so carpet fans, 450WHP is amazing. im sure he will make even more power with 2 more fans. an extra fan of air gave up alot of WHP as he mentioned.
This thing is a beast on pump gas im not going to be surprised if he begins to come close to the 500WHP mark.

Yea good point, and i meant close to 500, with your setup im not sure you can crack 500whp with race gas and some monster fans haha.. same dyno with a baseline and after results are best to see what you gained compared to the overall number you are making without a baseline for that dyno.
**** i wish i could make 450WHP for fun lol

My tq was high but don't know y. Even on the Dynodynamic he only used one fan pointed down to the bottom of bumper.
Sry guys every Dyno place I go to has NO real Dyno fans and they think they know where the carpet fans go.(bottom of bumper)

And then there's how the car is strapped down, too. Tighter straps = lower numbers.
And tire pressure. Higher pressure = higher numbers.
And wheel weight...
And gas used...
And...
But you get the idea. It's a big part of the reason a lot of mods don't make the claimed power on "your car" that they make for the manufacturer. (Not to mention the bull**** factor.)
Back to MThis' car... 455rwtq on a DD is a siiiiiiiick number. I'm still loopy about that.

I've been learning a little about dynos lately, and from what I can tell Dynojet = high numbers, but kind of inconsistent. The one at evosport would vary by 10-15hp/run and up to 30hp/session. (To be fair, it's in a corner with really crappy ventilation, but it seems par for the course with that type of dyno). DynoDynamics & Mustang = lower numbers, but repeatable. A friend that has a Bimmer shop has a DD and I've seen 3 runs back to back that are all within 3hp.

And tire pressure. Higher pressure = higher numbers.

Numbers are all over the place. The situation is not much different with dyno dynamics: we just found out that Autowave (a well-known and well-respected dyno dynamics shop in south California) raises their numbers by 11% to match dynojet numbers. It all depends on what the operator wants the number to show high or low. My dyno is posted in the W211 section but it was done a while back so may need digging up.

Actually Mustang Dyno and Dyno Dynamics can vary quite a bit as well..... probably more so than dynojets in some cases. For example, I dynoed my car at a Mustang Dyno (on a brand new machine with the latest/greatest hardware/software options) and got 500+ rwhp and the car is 100% stock. Bassn_07 dynoed on a Mustang dyno and got 447 rwhp and he runs 10.80s all day long.... Numbers are all over the place.

), but I actually meant run to run variability in the same session on the same dyno. My personal experience on a couple of different dynojets (with different operators) has been that it's hard to get a reliable baseline, even on multiple runs in one session. I can't comfortably say my car has 470 rwhp (just a number) because it's the average of five runs when the variation is from 455-480. I'd rather have five runs that read between 454-457 and say that my car has 455 rwhp. It's a lower number, but statistically valid. And if you know the correction factor on a repeatable dyno, then you have legit numbers to work from. Yeah, I'm a nerd like that, but there's a lot of claims made in this industry based on a single dyno pull and I'm starting to believe there really isn't much validity in that method.Just saying...
