The last part of the Flux-Capacitor upgrade arrived this afternoon. BTW, the garage radio is already tuned to my favorite ghey Smooth Jazz station.

 

i want that!

Wtf????

 

I have been working on my own tune for several months now. After giving up more than once, only to start again, I have finally done something I am happy with. Check out the max g/s # at the bottom.

Daaaammmmnnnnnn Nice!!!!
So what are your plans now that you've got a nice tune,,, Dyno...

 

I think I'll dyno it right before I rebuild, since dynos are so hard on motors.

BTW, those #s are with the original pulley ratios, a straight pipe in place of the cat, and MSD8247 ignition coils. I can get 300 miles to a tank if I baby it, and am getting at least stock highway mileage, if not better.

-Yambo

 

Watch the 88 mile per hour issue....
You may fry the tracks electronics if you cross the traps before leaving and don't red-light.

 

Man, you shouldnt give the Pettit secret out. Is that the Mr Fusion model or do you have to chase down the libions. It shouldnt be hard to catch that VW bus but you gotta watch out for them popping out the top with AKs.

 

411g/s this morning @8200 rpm

 

I don't get it . How can you get a number that high with the stock pulley ? What psi are you seeing at that point ?

 

well done.
incredible flow for std pulleys. have you upgraded the cooling or are running water injection? if so is it pre or post compressor?

 

It is not so much the boost(8-9 psi) as it is the tuning. Do you think that pettit is giving customers aggressive tunes? If they are, they wouldn't make it public for different reasons. If you equate 400g/s to 400 crank hp(which is reasonable, since some people say multiply g/s by 1.23), then that comes out to @ a 66% gain over stock. Many cars have achieved that %gain in the past with FI @ the same level of boost, or lower.

 

No water injection; I need to install mine before it warms up again. I think the tune is safe for now due to ambient temps being so low.

 

how is it that OD only sees 300g/s ish with the stock pulley ? If it is the same pulley as yours no amount of tuning is going to net you 100g/s .....

 

I am not going to argue with you. But just so you have something else to think about, I consistently saw 330g/s with my tune from pettit on stock pulleys. Search the internet, or whatever source you wish, and you will find examples of cars with @ the same amount of boost making 60% gains or more over stock.

-Yambo

 

BTW, my motor is tired due to 100k+ mileage and a few detonation events. Hard to believe isn't it?

 

If anybody cares to see it, i'll set my rev limiter to 9k just see what the max flow # is. Otherwise I'll just leave alone because besides the datalogs, the car actually feels quicker.

 

I consistantly see 320-330g/s as well... my highest was 338g/s
Do you have any plans with turning this into a flash for the Dude...

 

Very nice, lots of homework/reading = great results.

 

Bastage is on his way home after a grueling 12 hours of ghey smooth jazz garage radio background music. He is now a very satisfied Pettit Racing upgrade Super Charge owner. He is also running a header, blower and intake heat shields. We were able to attain 13 psi of boost with 11.4 A/F ratios (hence his 570 cc secondary injectors) based on the cabin gauges. He is currently logging on his drive home. With a little tuning I believe that he will be able to brake the 330 whp.

 

marsredr100,

great job!!!!

beers

 

Nice Job Juan and Gleynard!!!(sorry if I got that wrong its hard to remember your name Bastage)

 

I don't know how that would work.

 

very interesting Mork----can you commit why the maf voltage dropped on the last reading? That kinda puzzles me.
so you did a 15 sec run in 3nd gear?
true that i was pulling 305 g/s on the road race track
rest of data at the time:
engine temp 190.4F ambient 80F ( last part of a 20 min track section)
RPM 7547 !!!!!!
speed 129mph (5th gear) (holy **** turn 1 was coming up fast)
a/f 11.2
timing at 20 degrees
load 158
Ltt 1.56
maf 305.16
lower intake temp of 105F
i did have a bad coil(mazsport set up at the time)

just in case anyone was wondering about the rest of the data

Tune does affect power --for sure--that sure is a nice gain---intake vdi closed? Stock ports?
no cat I know---3" exhaust?
its more than just the tune I am thinking. you are running richer than I am. what is your timing?

also why wasnt your a/f's dropping when the rpm's were decreasing? 11.17 to a little over 12 was the only drop? You dont lift throttle much shifting? Dangggg! Dude--rip her up! Nice fast shift also approx 0.15 sec to shift---nice!!

bunch of us at the Mazmart gathering yesterday. Great time--sawa lot of differant stuff---height was speaking with Ric I the famous engine builder---saw a 4 rotor job with get this (STAINLESS STEEL ROTORS straight from Mazda and one of them costs as much as a 09 R3!!
they are not for sale but sure are sweet.
He laps ALL his side plates--they are NOT TRUE from the factory.
The Renasis has lose side seals for a REASON--dont try and tighten them up.
COating the exhaust port offers no benefit and would be very difficult to do.
Hasnt seen and real benefit from any rotor coatings.
Rotors themselves go bad--they dont last forever.
He really likes ceramic seals--but they are not really needed for a street/hpde car and just a low boost application.
Renasis power comes from getting tolerances right and general clean up--not much room to port anything---including exhaust.
Run heavy oil!!! 20w/50 he likes --ok with a 20/40 during cool months.
the pellet in the e shaft--not a question of if it will fail--only a question of when. watch the oil temps.
loosen the alternator belt just a tad and let her warm up good in the mornings.
HE has ran aluminum side plates!!!! Someone has some now!!! ENgine looses a LOT of weight with them.
He had several questions about our water meth systems---and gave a nod of approval.
cant reduce compression on the renasis--rotor face too thin
Like the EFI dude
Says Hello to Cam!
Great day--Mazmart thinking about doing this 4 x a yr.
The omly bad was they had not inventoried the 09 car so i could not get the fp.\
