My mods are HPTUners, CTI header/downpipe, Corsa Touring Catback, Injen intake, Cometic headgasket, Golden Eagle Headstuds, flowmatched 60lb injectors, 2.6" pulley, ZEX plugs, Exedy clutch/flywheel, AEM UEGO, Driveshaft Shop Stage 2 axles, Ingalls TD, B&M shifter, SSC springs, and 17" Rota Subzeros wrapped in 235/45/17 Toyo T1R rubber... and I think that covers most of it.

The Good: I got my car dyno tuned today!
The Bad: My nice CTI header/downpipe combo now has a clogged high flow cat!
The Ugly: After 4 hours of tuning we finally figured out what the hell was going on an why the car was so difficult to tune. The header got so hot from the cat getting clogged somehow that it was glowing orange/red! Needless to say I'll consider myself lucky once again, and fix yet another issue. I will be removing the cat tomorrow and adding a straight pipe where it resides. I'm also offically broke because of the ordeal taking so damn long! Dyno tuning is real expensive! We shut the car down early on the last few runs as well since it wouldn't make anymore power up top due to the exhaust not breathing, so the run ends at 6750.

The second dyno graph is a comparison from when I just had an intake. This Mustang Dyno is called the "Heartbreaker" for a reason. It tends to show around 15-20whp less than the local dynojets, but it's where my baseline was done at so I use it for comparison sakes only. The first dyno was done when it was a lot colder out as well. Without further delay the graphs.

 

Can't see what you made........

 

^^^x2

 

238WHP and 230WTRQ. Sorry about that, the scan came out light.

 

those are actually great numbers for that dyno then,I was just on a heartbreaker dyno recently and am about to go on another that shows stock ss/sc at 189whp,All dynos are different all you can do is compare your ride to another that has been on the same dyno

 

ouch that sucks, my TOG header would glow after a hard run at night. Goodluck with that.

 

Thanks bro. As for a car race comparison, let's just say before this semi final tune I had a run at 231whp on the same dyno and gave a C5 Vette a surprise as he didn't leave me. In fact my buddy will contest that if I didn't have to let off, I would have passed him while still winding out second gear and kept going on. I was at his door around 5000rpms and still pulling in second gear since I rolled from 20mph in second in order not to spin!

 

ouch those numbers are low , you have EVERY mod you can get accept the intercooler , i would love to have axels and a clutch

 

shouldnt that number be A LOT higher with those mods????

 

go back again for a run when you have the staight pipe,i just did the same yo mine and im going catless now too!

 

Seriously bro, do you guys not read. He said it was a mustang dyno, They tend to be 20 to 25whp lower than regular DYnojets. He is actually making 270 to 280whp on a dynojet which is freaking awesome for his mods. Add meth and a 2.5" and youll have a 300whp car

 

Ljavy, I made 244whp on a mustang dyno and ya know what, my mods arent close to his!

 

I don,t know why we bother to post dynosheets,every dyno will be different period.

 

Very true.

 

mmm... listening..since my mods are very similar

 

His torque numbers are real nice. My numbers are in my sig..I think his HP numbers will go up a good amount once he fixes the clogged cat. If my damn cams and valve springs ever come in, then I will have some new numbers posted up with them, injectors and a good dyno tune. I don't have any aftermarket exhaust yet though. Uggg..Yet another mod to get. Not bad though man

 

GET RID OF THE STUPID CAT!!! WHY WOULD YOU DYNO IT WITH THE DAMN THING ON!?!?

 

I dynoed on a Dyno Dynametrics which reads lower #'s than a normal dynojet and at the time I just had catback and tune, I made 238hp and 205tq, im goin to the dynojet soon. But on the same dyno an 06 completely stock got tuned to 258hp it must have been a factory freak...

 

go figure,dynos are starting to look very innaccurate

 

Who cares what his actual numbers are.....

Look at the second pic, where it shows his old curves versus the new one and it is DAMN impressive.

Looks good 2K5, sucks about the cat though

 

Thanks Retrop.

Guys, I do think it's the cat. The car is not overboosting or anything like when it happened the first time. I think the header was just that hot because of the car being on the dyno for 4 hours straight doing god knows how many pulls. I talked to the guys at TAG and they said my timing should be higher than it is. That is probably why my numbers were lower on top of it being a Mustang Dyno. I'm going to do a little road fine tuning tonight.

 

nice numbers...

 

Thanks bro. I just upped the timing a little and made some other minor changes after some reading. The car seems like it's a bit quicker too. Now to do figure out datalogging so I can check my progress better!

 

whats ur timing table like. PM me, How much timing in top end.

 

It was at max 16* in the top end. The gents at TAG said it should be higher, so I did a little increase tonight, and a quick spin says they were right! I fought for 2 hours trying to figure out how to data log, and I got no where. I need some serious help in that department. This tuning stuff can create one hell of a headache!
