BBK Full / MAP Stg3 head / Aquamist HFS-1 Dynojet results

[scheides]

MitsuStyle.com fall dyno day at Modern Automotive Performance in Plymouth, MN. I threw my car on the rollers to see what the lil BBK would do on pump and alky.

Here's the sheet MAP printed off. The tach signal to the dyno kept falling off mid-pull so this was the best they could give me.



One run on pump was 430whp, I'll have to get that one out of them. The car performed very consistent, I'm very happy with the setup now, specifically my boost control setup. I didn't have error correction on when I was at DB last time as we were dialing it in for the tune and then I dialed in boost correction on the street to make it as perfect as I could. As a result, I compared logs and am running about 1psi less on this dyno session (on pump gas) than I was at shane's. Not a huge difference, but notable I guess. It's almost exactly how I run it on the street so I'm happy AFR's 11.0 spot on. Timing was roughly the same as my dyno session @ DB, perhaps 1° lower in spots.

On the alky map boost seemed almost spot on with how I run it on the street. Timing was about 1-2° lower than my 432whp tune at DB, I'm guessing due to the different loading characteristics of the dyno (this puts it around where my car put down 420whp on DB's dyno). I also changed out my brandX meth 50/50 mix with VP M1 mixed 75/25 with water, so AFRs went from ~11.8 to ~11.3. I will be switching back to 50/50 I think. It was worth a shot but it didn't help me on the street or on the dyno at all.

Overall I'm happy, the car is consistent and running strong. I would have liked to get closer to or break 500 but meh, last minute changes FTL, plus my luck sucks so I'll never be the guy who magically makes extra power. I'm NOT pushing the setup hard so maybe next year push the turbo and timing a lil more to fill the gap b/w me and the FP red guys running 33-35psi and making 515-520whp

looks great!

we only run 50/50 on alky... there are some different theories on this, but with pump gas the added octane from the water seems to help more than running more alky in itself....

also, when i run alky i tend to run the car at 12.0-12.2 AFR

so i wouldnt be surpised if you picked up another 30whp by doing so

Ya, on 50/50 the car runs closer to 11.8 and had this not been just a dyno day I would have tweaked it to run a bit more timing, so there's certainly 500whp in it at this boost level.

Thanks for an awesome product man, I gave my mom and dad a ride in the car when they were visiting me last weekend and my mom was happy as a clam in the back seat and dad was asking where the nearest Mitsu dealership was (i.e. he wanted one). There were two FP Red cars at the dyno day, both of them had blown once in teh 6-8 months they've owned them

my car was tunes for 100% alky now maybe im thinking of doing 50/50 or 70/30 mix but my tuner and shop said it's better to run 100% very confused been seeing this made my think different what's your thought's?

Read this. It will answer all of your questions:
Injection Mixtures 101

Ultimately I have tried all of them and saw an imperceptible change, so I run 50/50. It's cheaper and won't 'splode

hahahha good point ill read and let u know thanks bro...

Nice results.

I'm curious if you log MAF Hz or lb/min? What boost?

[scheides]

I didn't log airflow on these runs, only boost, afr, timing, rpm, knock, etc. Peak boost was like just shy of 30 on alky tapering to like 26@8000 and just above 24 and holding pretty much flat on pump. Maybe like 24.2psi avg.

I'm trying to get some of my other runs that were made where the tach signal kept cutting out, and maybe an uncorrected run on alky. I'll post them up whenever I get them.

[RockmanX]

so your shooting for 500 on pump gas + alky? or only on race gas?

[scheides]

No race gas, the car sees BP93+950cc's of 50/50 meth/water daily. Like I said 500 would have been nice but just tossing it on like this and zero tuning on this dyno I'm happy.

dont you make around the same power as john F from MLR? you should be able to kill a slightly modded 997 TT or GT-R with that car since it has more power and less weight then either car

[scheides]

who's john F form MLR? Funny how when I was making 432whp on dyno dynamics no one realized this, but now 480whp on a dynojet is 'enough' I have a friend with a k24'd 993 and we have yet to test & compare but ya, the power is certainly there.

Ahh yes, he and I discussed our setups at great length. He's short on power compared to me, but I was running more timing and a few different parts. Very nice guy.

[Bosshog]

It just seems that the dyno figures in the states are not comperable to the ones over in europe. If you made 420-430 DD in the UK, you would have a car that should beat a stock (hardware wise) but tuned GTR or 997TT That equates to 550HP - 10% more power than a Z06 which trap at 125mph stock
