I dunno, my goal is to have a car that I enjoy driving and taking to the track. And, I mean, clearly, to have one of the finest looking pieces of sheetmetal out there. I think everybody on this board shares this goal. No more drama please?

Agreed!

 

I got the Dyno run files, but no program to open them.. I had to try and scan the original printouts..





This last one is me against a 2005 Mustang GT with a Performance tune, with a new CAI unit.. I'm the blue line.

I'm 310RWHP 314RWTQ-------The 2005 GT is 303RWHP and 326RWTQ--On its surface, I would say that GT has a darn good tune and a good CAI! [img]style_emoticons/<#EMO_DIR#>/thumb.gif[/img]



I know these suck, but they will have to do until I can figure out how to open the original runfiles.. Sorry guys!

One more thing.. The GT would be a really good race for me.. We are pretty close.. It would definatley go down to the wire... [img]style_emoticons/<#EMO_DIR#>/dunno.gif[/img]

 

Also notice how the dyno driver did lift before 6000RPM... I am positive I could have gotten more HP on that run, because of this he lifted around 5500rpm.. I did run a test today in 1st and 2nd gear.. I do reach a full 10psi @ 6000rpm on the money...

@Max200Jp

Thanks man!! I learned something new today because of your debate.. I tested it and you were absolutley right.. Thanks for sticking to your guns.. I dont profess to know everything, thats why I come here to learn..

Your insight tells me I got short changed at the dyno, cause the driver was lifting before 6000RPM and was not grabbing all of my 10PSI of boost... I think he is full of BS about the 4500RPM @ 10PSI.. Its impossible.. Your right! Once again thanks!! [img]style_emoticons/<#EMO_DIR#>/thumb.gif[/img]


Also, notice in the run with the GT, the GT got to pull all the way to 6000RPM.. I only pulled up to 5500rpm or around there... 500RPM may not make that much of a difference.. But when I tested today in 1st and 2nd, I was not at 10PSI @ 5500rpm.. Only at 6000RPM...


Maybe someone can help interpret these, and give their opinion... [img]style_emoticons/<#EMO_DIR#>/dunno.gif[/img]

 

MSP,
thanks for all your posts on this subject, gives someone like me somethings to consider before buying one.
The A/F ..... yours is dropping below the chart? Is this a concern for you?
Thanks.

Remember those discussions we had with Mike... way back... I think we decided we really don't want to run the RPMs up so high... Think we were talking about keeping the RPMs between 5500 and 5800... definitely didn't want to push past 6000... My car is setup to shift right around 5800...

One other thing I noticed on your A/F... something we never talked about before.. open loop vs closed loop...

If you look at your A/F you'll notice it stays up for while and then dramatcally drops.. I belive this is where the goes from open loop to closed loop... The car has a built in delay for this... Lidio really lowered this on my tune... was wondering if anyone else has noticed or done this... The following dyno shows the difference...take a look at the two different A/Fs... See how fast the Red A/F drops compared to the Blue?

 

@MSP,

Thanks for posting these!!!! Those numbers are very strong!!!! I really can't wait to hear how you do at the track. I was looking at your mods and wanted to ask you a question. Have you given some LCA's a thought? And, how is your tlok performing, I know the SC is the star of the moment, but you got some other cool mods and wanted to know how those 3.73s felt with the tlok and sc? Again, congratulations on your GT350! You need GT350 side stripes now. [img]style_emoticons/<#EMO_DIR#>/thumb.gif[/img]

@Scrming,

I remember the conversations we had on where to make safe power with the 4.0. But I do have to ask, Vortech offers a high quality complete kit with a 3 year warrenty. If they are making power at 6K, maybe they know something we dont? I mean, they wouldn't put a kit on MSP's car just to have it potentially damange the car at 6K. Maybe we should ask Forced what thier experts think of the 4.0 at high RPM's. This would be a good time to get another opinion on our rods/pistons/heads/cams as we have speculated on this many times.

@Forced,

Can you provide us with some insight on these items?

 

Vortech sets the tune to 10.9 A/F, for engine saftey reasons.. So the tune is set rich by Vortech.. Setting the A/F @ 11.9 or 12 should mean another 25RWHP and torque.. So my actual numbers are alittle lighter because of the 10.9 A/F...


Thanks Hambone!! [img]style_emoticons/<#EMO_DIR#>/thumb.gif[/img]

 

I'll post more later, once I figure this thing out! Hambone you Rock!! [img]style_emoticons/<#EMO_DIR#>/icon_mrgreen.gif[/img]

No problem. So you are getting 10PSI at 5500? That sounds about right. I am sure that you can't get the most accurate reading while trying to shift and look over at two gauges. I bet it's right about dead on. That's why I love my buddies boost gauge that has peak hold. I looked over you dyno and you have a lot of power that can be made leaning out the tune. A boosted engine should shoot for 11.5:1 to 12:1. He tuned it really rich, which makes it safer and produces less power. I bet there is 15-20whp left in just a tune.

I also looked at the dyno of the GT vs S/C V6. If you raced from a standstill based on the dyno, the GT would pull you. The GT has the advantage under the curve where it counts. Up top, I think it would be about dead even. My car trapped 108.4 and 109.1 making roughly 300whp(never had it dynoed).

 

Ok guys! Here is my first and 2nd pull.. The method is using the STD.. Which is the average between Uncorrected and SAE!



These runs were done about 5 minutes apart from each other... Not really much time to cool down..


Here is the pure SAE version!




This is showing the 3rd pull... Total time is 3 pulls in 15 min.. The Supercharger was extremely hot... As you have seen in the video, they did not have a fan in front of my car... The the radiator for the Charge cooler had stagnet air, as well as the radiator for the engine... So basically no air flow being forced through the front of the car...




It appears to me the V2 and Charge cooler are really efficient.. This would be equal to 3 back to back 1/4 mile runs.. I would guess at an average track, it would take about 5 minutes to get back to the christmas tree after a run? Maybe longer?

Also, looks like my 2nd pull was the best...

Here is is again in STD mode.. With UNCORRECTED to follow..

 

MSP congrats on the numbers. I bet the horsepower difference between your car and Belial's is all in the tune. I bet your car with an Xcal2 and some dyno time with one of the good tuners can get to 350hp at the wheels. Good Luck

Good luck [img]style_emoticons/<#EMO_DIR#>/thumb.gif[/img] , dont forget to take a couple of bags of ice so that u can take full advantage of that aftercooler. When i fill mine up at the track , it will still have ice in it after the 1/4 mile run , so u know it is working. Probably get 15-to 25 more horsepower with the ice in there depending on your timing tables for air charge temperatures.

The ice should last the entire 1/4 mile run , just get a refill after every run. Did u use ice at all during your dyno runs?

I would really love to see Belials numbers with 3 pulls.. I think he is still working on the tune somewhat.. Hopefully he can make a run like me, with 3 pulls in 15 minutes... With no front of the car fan! LOL!! Atleast we could compare the Vortech and the ProCharger together... I am quite sure Belial's tune does not consist of a 10.9 A/F ratio.. So i'm quite sure he is making more power than I am right now.. [img]style_emoticons/<#EMO_DIR#>/thumb.gif[/img]

 

I looked at the second graph and from what i can see your A/f goes mega rich when u punch it and gets better as boost builds. If you can get your curve like this , your car will get going much faster when u step on it. It will still be a good A/F at 11.5 and will get richer as it reaches redline.

Yes, Vortech set the SOHC 4.0 up like this for saftey reason in the Diablo Tuner.. We all know the car can handle more power, and they do to.. They said it should last forever with this tune.. Its quite safe for the duration... Vortech is not willing to sell the kits with the A/F greater than 10.9.. This way customers cant blame them if the motor is hurt above this level.. So I, as well as Vortech know the tune is rich...

If I were to add a smaller pulley, lets say one size smaller, that should be good huh? Lets say a 12psi pulley? That would put me at 378HP SAE roughly, although and with the A/F raised to about 11.5 from more air being forced, I should be at about 403HP @ the flywheel SAE and about roughly 342RWHP.... What do you think?

Just made another video... Hopefully it turns out ok! I'm uploading now..

 

Ok guys!! Its a big video.. Cable modems required.. Also, my exhaust is so deep it really pounds my camera, sorry.. But you will get the idea.. Notice when i walk up to the car, my speaker tries to jump out of the camera, for fear of being blown!! LOL!!

Good luck downloading!!

I prefer the clean A/F curve and the conservative timing approach, feels better in my opinion , specially on centrifugal blowers, more pick up power. Yep u can always lower the pulley size and add ice, but even there a cleaner curve would help , diping into the 9s is a bit extreme on A/fs.

Wow, there is so much deep rumble comming out of your car the vid camera can't handle it. That Vortech looks beautiful, I like where you mounted the guage, out of the way. Goring for the sleepr approach eh? Very nice. I bet this thing sounds insane in real life.

Yeah.. I understand.. We tried to re-tune the Diablo Predator, but its a no go.. I will have to get an SCT2.. Your car is sweet man!! Looks like there is not much out there that worries you! LOL! Not much at all!! Nice job! [img]style_emoticons/<#EMO_DIR#>/thumb.gif[/img] [img]style_emoticons/<#EMO_DIR#>/icon_mrgreen.gif[/img]

Yes in person, it does sound really darn good.. I knew the series 40 Flowmaster hooked behind the Prochamber would be the perfect setup... It sounds real smooth and deep.. Its really perfected as far as I am concerned.. Not obnoxious at all.. It just sets off every alarm within 50ft of the car @ 1500RPM! LOL!!
