Streettunedmotorsports.com has given me free reign of there dyno last Friday morning and afternoon. Last year we put down 355hp on a conservative tune while running 100% duty cycle on a set of Denso 660’s. This year things are a bit different.
Handling the fueling this year is a brand new set of FIC 1050cc injectors which are big enough to be corn ready if need be. The car has also been running ECMlink speed density for a week now so we can finally put that GM MAF where it belongs. The trash!
The goal for was to get the car back to 355hp and then dial in the cams using the adjustable cam gears donated by Autobahntom. From there we want to play around with advancing both cams to see if we can’t push the power band lower while still holding onto the 355hp target. All while limiting ourselves to 25psi of boost. If there is time and the car is running right we might crank up the boost to see what she will do. Last year we had a boost controller error (I set it wrong) and we did a 30psi pull which netted 377hp at somewhere between 5-6k rpms. So we know there is lots of power left in her.
Friday morning starts a bit late and most of the time is spent dialing in the VE tables in the ECMlink software. Once I get those dialed in its time to start some real pulls with boost. Just as I am almost done I can hear one of the chains tapping on the side of the dyno. At first I didn’t really bother with it but then it go louder and louder. I hopped out of the car and had one the STM guys rev the car and it wasn’t the chain. It was comming from under the hood!
It seems to scale with rpm which is bad but it goes away when the clutch is depressed. That is good but not so hot for the transmission. Yep, something let go inside my tranny. Good thing I was local on the dyno and not half-way across the country.
Emery at STM did everything he could to help us out. He tossed me the keys to the F350 shop truck so I could run home and get my spare transmission and then cleared out a bay in his shop so I could have a space to work. He said “no worries, we’ll get this done..we have enough hands here.†So I spent most of Friday night pulling the old tranny out and installing the new one with a lot of help from Cory and Kevin at STM who helped me wrestle the tranny into place. I also found a loose spring in the ACT street disk and Emery got on the phone and had a low millage disk at the shop in a couple of hours for me. At Midnight it rolled out and I brought her home.
The RochesterDSM One Lap team owes Emery at StreettunedMotorsports.com a big, big Thank You! for basically opening up there shop to help us out.
The dyno time was rescheduled for Monday after work. We started out with more work dialing the VE tables in and getting that map to look right. Emery joined in and we started to make some pulls. A quick low boost run netted 275Hp and told us everything was running right. So we put the boost up to 25psi and make a quick pull. That got us 351Hp which is almost as much as we got last year on 27psi. A new set of plugs and a few more tweeks gets us into the 360’s. Another plug change and advancing the intake cam gear 2 degrees gets us to 368Hp with a much better torque curve. From there we adjusted timing and boost to get to the 370’s, 389Hp, and at 28psi of boost it made 401Hp @ 6400 rpms and 366 torque at 5200 rpms.
Knowing the One Lap EVO X put down 402Hp on the same dyno we decided to give the boost controller another twist to see what she had in her. This time we had a bit of knock up top which dipped the Hp/Tq numbers on the top end but still netted us 408Hp @ 6300 rpms and 386 ft/lbs of torque at 5100 rpms. The Hp curve was still climbing before the knock dipped it down a bit. If we were able to take some more timing out up top it would have made much more but 408Hp was good enough for us especially on a Mustang Dyno. The boost curve showed that we had 33psi at torque peak and it had dipped down to 31psi at Hp peak.
There’s no way we are running 33psi of boost for this race. Its just too much power for our spare tranny with its stock center diff. We’ll be around 25psi which should put us in the mid 360’s which is more then last year. We will also be on speed density so no more GM MAF hiccups.
Big thanks to Art Hoffman, Forced Performance and TeamNABR for helping us out and loaning us the FP3052 turbo. For some photos be sure to check out our website here. http://wp.me/priSZ-sk
