I've been running the car for a while now with the stock MAF, stock block with Kelford 272 cams, and a BBK-Full turbo. I've put about 10,000 miles of track time on the car at NASA HPDEs working towards my TT license. The car has been a blast on the track, but I made the poor decision when I put in the cams to reuse the factory springs. My last event at NJMP my coach and I ran the car for 20 20-minute sessions over two days, and in one of my last sessions I spiked the motor to 8k+ rpms passing a Boss 302. The result was some nasty valve noise as the pistons slapped around the valves in cylinder #1.

I dropped the car off at Agile Auto who have done all the work on the car and they pulled the head to fix up the damage. At Hill's recommendation they sent the head off to Head Games for porting and a full Ferrea valvetrain . At my current boost levels I decided to leave the bottom end of the motor with stock pistons/rods for my last event of the season before cracking the motor again for a 2.3L build. In preparation for that build we decided to swap the car to speed density, and retune with a 4'' intake, 3'' downpipe and o2 dump. I went with the MAPerformance o2 eliminator pipe as it met those needs perfectly and Agile fabbed up a 4'' pipe with a K&N filter.

I'm extremely happy with the results, as the car made an improvement in peak numbers, but most importantly a huge gain in area under the curve. Where my torque used to peak and drop like a rock, it holds for the bulk of my power curve now.

My previous results are here: https://www.evolutionm.net/forums/ev...93-octane.html

The car now makes 444 awhp and 374 awtq on pure 93 octane with 0 knock. With speed density the car pulls so smoothly in boost now its crazy. The peak numbers really do not give this car credit for how insanely fast it feels. I'll be testing out the changes at Summit Point, WV on November 3rd-4th.

 

Congrats, a modest setup that can be used and abused, and driven home to.

 

Nice setup. Im planning very similar mods, hoping to have a high mileage daily driver. Still at 26lbs? I guess its kinda hard to tell, but how much difference do you think the head porting made vs the other mods?

 

Very nice. Same dyno as the previous results? Will you run it just like this at the track or tame it a bit? That thing will scoot at 5k and up where it used to die out. What are ur plans for the 2.3, turbo-wise anyway?

Also did u get the contoured flange downpipe or the standard? I have the standard flange and boost gets a little nutty around this time of year. I have a 3 port now so its controlled, not creeping anymore, but it likes to raise up a # or so once weather drops below 50. Its a trade off...boost holds extremely well (like maybe 1psi taper) but there's a degree of unpredictability as well

 

Same dyno as all my previous dynos, I generally start my sessions with the boost turned down a tad, until I get into the groove and turn things up. I run cut 100 octane at the track for safety sake. Initially I'll be running the 2.3L with the BBK still, although I will probably get an anti-surge cover. Down the line, I'm thinking a full CBRD turbo kit, but honestly I don't need more power right now. The car is ludicrous on the track, and I'm only planning to build the 2.3L because I'd rather be safe than sorry with stock rods at this power level, and no point in doing a 2.0L build if I can throw in a 100mm crank at the same time and pick up 11% torque for free.

I have the 3d contoured flange and it seems fine, but I haven't gotten a ton of time to beat on the car yet. I'll let you know after Nov. 3rd-4th how it does.

 

Is that on Agile's dynapack? That specific dyno tends to read a little high in my experience from multiple comparisons.

Awesome power curve by the way, that thing does not let up ever! haha
Nice track setup, keep it up.

 

It's on Agile's dynapack, however in my experience I have found the opposite to be true. It reads surprisingly low for a dynapack. For my mods and boost level I'm closer to the numbers I would expect to see on Chad's dyno. For whatever it's worth, the VD numbers on multiple runs turned up results that were within 2 hp/tq of the dynapack results. I don't know if the VD defaults to Dynojet or MD numbers, but whatever the default is turned out 442-446 on every run.

The power curve is crazy, it makes it feel far far faster than the peak would indicate.

 

VD defaults to Dj numbers.

This car looks to be exactly what I would be looking for in a street car. I could only imagine the power it makes with an aggressive tune since you have it set to run on a road track. Awesome results!

 

the dyno discussion again

agiles definetly is up there a bit- but the numbers are still good regardless.. and I'm glad you are happy!! I bet its a blast on track!

I want to come up there sometime to see if thats actually true. If VD numbers are generally excepted these days as "accurate" its dead on what I'm seeing from the dyno. In any case, its definitely a blast on track, its stupid fast.

 

sure thing- id love to have you come up-just pm whe its convenient.

444whp would make it the highest bbk full pump gas car ever on our dyno

Dynapack dyno numbers are similar to VD numbers.
I've tested this with my car.

The OP's dyno sheet is "flywheel" power, so I feel it's probably 15% higher than "WHP" numbers.

 

All dynapack's say that, but it's actually at the hubs.

 

dynapacks always read higher then dynojets, and no comparison to mustangs. the curves look good though. the torque curve is what will make the car fun. nice and flat till redline.

if you're happy with it thats all that matters.

 

Hmm, tscompusa, I thought the VD mode in Tephra was Dynojet equivalent? I don't have a screenshot of the output from that, but it was identical to my plot. I know that Mustang dynos will always read lower than a Dynapack if nothing else because of the wheels and possible slip.

In any case, I've only had the car dynoed on the same dyno since I originally got it, I guess its been dynoed 4 times on this same setup and I've seen steady gains the whole way through.

I started at 330/300, then 390/300, then 407/368, and now 444/376. My next step will probably be with 2.3L and 93 octane.
