the dotted line is your a/f? looks like a mountain range.......

 

nice numbers, those test pipes and dual exhaust are probably really helping you out - how loud is it? It's probably louder than my car I'm assuming. I bet with high flow cats, your boost pressure would be more like 10psi and less power

that sudden jump where you're going lean is just a glitch - probably with the throttle. Nothing would ever jump up that quick


to the naysayers about the dynojet conversion:
joedirt tuned at dynocomp, then went over to a local dynojet place (called Dynochip) and made like 11% higher numbers on the dynojet so that's right in line with the ballpark 10% inflated dynojet numbers

 

I agree totally . Thats A/F doesnt look good at all . Your getting rich enough towards 6500rpm , but the rest should be a smooth line heading down ward

The power and trq. curves look nice and smooth though . Maybe he did the A/F that way on purpose..dont know ??

 

I will ask him the next time i get her tuned... I am considering going with the Kinetix SSV soon so I will have to get another tune done.

I hear that the SSV is bunk for N/A but with FI it should give some pretty good gains... I talked my shop into giving me a SSV to try out and get a tune w/ it... They will pay for 1\2 the tune and I will buy the SSV is it makes more HP & TQ than the Crawford...

Otherwise they will pay for my re-tune to the Crawford and take back the SSV...

Not a bad deal if I do say so...

The AF on that chart is all over the place but is much better then when I first got there... I was running pig rich at 9.6 at WOT before the tune... She runs very smooth now and the pull is great!

 

yeah the A/F is within the range it should be though at least. The SS box should still have enough resolution to smooth it out a little.

for comparison (since our cars were tuned on the same dyno within a month or so apart) I'm looking at my 3.12 dyno graph and even though I wasn't fully tuned (I still have yet to get fully tuned) you're making roughly 0-2 psi more than I was with the 3.12 pulley though from 3000 rpms to redline. Though at that time I made 373whp and had more midrange power as well. At the time the top end detuned because of my lean condition hitting 13 A/F (thank god for racing gas)

 

I would skip the SSV , unless you like the bling factor . Was the deal for the SSV made before he did this tune ????

 

The SSV is a POS. N/A or FI you won't make more power! I can't believe people still buy that thing.

 

+1 i've talked to people who have it, doesn't make a diff to them. Looks nice though.

 

I wouldn't pay $800 for something that looks nice, but robs power from my car especially after spending $6K plus for an FI system to make the car faster!

 

well if he's wanting to keep his strut bar and run the vortech and still upgrade something with the plenum, what are the options? You can't use an APS, stillen, or crawford strut bar with the vortech kit

IMO the SSV is better than the stock plenum, weighs 10 lbs less from the top front of the car, and looks cool, doesn't trap heat into the heads as much, makes it easier to change things like fuel rails and injectors cause it's just 6 bolts instead of 18 or whatever with the stock one. You can also actually see one of the fuel rails and a row of injectors to see if there's any leaks or anything - also it looks nice to see your aftermarket fuel rails.

in my case I can also use a thermogasket because my engine is 1/4 inch lower in the engine bay because of my solid motor mounts

 

Please post your results of you tune, SSV vs Crawford. I have both and cant decide which one to use with my turbonetics kit. I'am having the turbo kit put in at the end of the month. I installed the SSV on my car this week and it ran like crap. For N/A cars crawford pulls alot harder. I ran a 14.0 at the track with the crawford and a 14.5 with the SSV. Curios to see the gains with FI...

 

I'll post the Dyno for the SSV and the Crawford... both will be tuned at the same place within a couple of weeks of each other...

It is a win / win situation for me... I am getting the install pretty much for free on the SSV and they are paying 50% of my tune w/ the SSV... If it does not make more HP and TQ they will take it of and put the Crawford back on for me and re-tune...

I can't really beat that offer now can I...

And this will once and for all tell the truth about the SSV vs Crawford in a FI car.

 

you have the latest crawford cast plenum right?

i'm interested to see the results

 

Yes, I have the latest cast Plenum...

I tell ya what that Plenum is a heavy SOB as well... weighs alot more than the stock Plenum...

Hey Sentry... You going to the Pavillions tonight? Alot of us are meeting there at around 8PM.

 

A 5/16 plenum if the strut bar is a concern.

what good is 10lbs lighter if you are being robbed of 10-20whp?

maybe if I was all about show, but again I wouldn't spend $800 on the SSV after spending thousands to make more horsepower with other mods.

 

what kind of fuel setup do u have?????

 

i'd love to go, but my wife and i already have plans

that's interesting that the cast plenum weighs more. I wonder if it's made of iron or steel instead of aluminum?

 

whoa, do you really think it is that much or have people just not really tuned for it. Seems like the people that have even half attempted to tune for it lost only like 5-8whp

i dunno, maybe for people with 600whp, it might make 10-20whp less than a crawford

 

I have the stock fuel set up and what came with the full Vortech Kit.

I am thinking about upgrading in the future to 440's and a Walbro pump... Prolly when I do the Cams, pistons and rods.

I am also thinking about going with the E-manage Ultimate as well.... The SS box is very old school to tune as well and very slow where as the E-manage is live.

 

I can't remember the guys screen name (it was a while ago), but he installed an APS TT, had it tuned, and then installed a SSV and retuned it and lost 20whp. He was in the low 400's on a stock motor. He then put on the APS plenum and gained 30whp with a retune.
