Car back from the dyno shop!

RuffCat -> Car back from the dyno shop! (4/28/2008 3:40:39 PM)
Well, I dropped the car off at the dyno tuner and will be picking it back up on saturday. I had no choice but to leave it for a week because of my schedule and his didn't match up. He does it as his hobby and 2nd job so he wanted to do a few cold run and hot runs with each tuning improvement. No sweat cuz he had 4 Z06's, 2 Termie's and 3 other LS1 cars in his shop. I can't freakin wait!!! He has a brand new DynoDynamics dynomometer (mustang stykle dyno)(Real numbers) So, I have a 96 cobra with BBK LT's, O/R H-pipe, Magnapacks catback, JLT RAI, BBK 62mm, TR-6 plugs gapped at .055" with accel coil packs. I have some 315's out back that will put a 'lil drag on the rotating mass, but all-in-all the motor has 55kmi on it so what should it run with a 93 octane SCT tune? As soon as I get the slips I will take pics and post them up. I'm hoping to break 300rwhp and 310rwtq? Is it possible?? Let me know what you guys think so I don't see 250rwhp and have to fork out a couple hundred $$$$.....lol I'd be pissed UPDATE IS BELOW!!!!!!!!!

I say 293 rwhp. Just short of 300- sorry dude but that is my guess quote: ORIGINAL: RuffCat Well, I dropped the car off at the dyno tuner and will be picking it back up on saturday.

I say 285 . If you see 250 RWHP youve got something seriously wrong.

BigSwaug -> RE: Car is at the dyno shop! (4/30/2008 2:38:19 PM)
how much is it to get it tuned and dyno'd? im looking to do that soon so im just wondering how much.

BigSwaug -> RE: Car is at the dyno shop! (4/30/2008 2:39:20 PM)
also does anyone know where a good place im michigan is to get it done?

RuffCat -> RE: Car is at the dyno shop! (5/3/2008 6:05:46 AM)
well i've got something wrong with spark at the time the IMRC plates open up. The power curve drops like a rock right at 32-3300 so I'm only picking up 250ish. I have to go down and see what is going on. I'll just put my deletes in them and get the tune done with them strapped open if we cannot solve the issue. Those IMRC plates are a PIA for tuning because of the many spark adding tables that are invloved. I'll keep ya's posted

RuffCat -> RE: Car is at the dyno shop! (5/3/2008 12:39:11 PM)
alright, went to the shop and fussed around. The dyno guy is all gm and isn't familiar with the 96-98 cobra IMRC crap. He didn't want to mess with all the extra saprk tables that are needed when the IMRC's open up. I had to wire tie them open for now. He didn't do any better than the canned tune that I had initially. He changed the air/fuel from 13.6 that it was running to 12.7 and added a tiny bit of spark from 22-2600rpms cuz it was dropping a little. I am kinda dissapointed. It ran 268rwhp and 272rwtq on a Dyno Dynamics Dynamometer. Aren't most guys running this bone stock? WTF

RuffCat -> RE: Car is at the dyno shop! (5/3/2008 12:55:04 PM)
I did want to add that the IMRC flow was 1058 for one side and only 568 for the other while they were tied open (clogged)??? This tune is 23degrees total timing at WOT is this good or can these motors run more? 93 octane I have Plastic delete plates that will be going in next weekend and back on the dyno. I will take a pic of the sheet and post it in a few hours

Pull out the Imrc's, I had mine zip tied and I noticed a huge difference between no imrc's and zip tied.Get gears and you wont notice I was hesitant to but its really working good for me.

Did you get gears the same time as your deleted IMRC's??? Then it would have obviously felt diff. I do have deletes ready to put in. Also I have 3:73 gears and that's as high as I will go. I put them in last year and I'm NOT doing them again. Plus my exhaust is ridiculous on the highway already and I like how I can cruise comfortably in 4th gear at 50mph where as with 4:30's I will have to shift to 5th. I drove my boys with 4:30's and just didn't like it. I had to shift way to fast through the gears, especially in 1st. It drove me nuts. I hate tricking myself into feeling power. I just want it! Ya know. Maybe I'll get a KB twin screw??????

Ehmark -> RE: Car is at the dyno shop! (5/4/2008 10:43:05 PM)
I got the gears months after I did the delete. I still felt a difference but I did port match them while I had them out.I was thinking about a KB but I am not too fond of the whole no intercooler thing particularly on my stock short block.

What kind of Dyno did you get your car done on for your numbers? dyno jet, mustang dyno??? Thanks I have the 98 IMRC's so I'm hoping I won't have much if any port matching to do. I think I'm gonna leave the hole in the middle of the ports open for some mild turbulence to help with atomization. I just don't see the need to fill them and don't think it's worth the risk of having epoxy falling out of them because they are very small.

Ehmark -> RE: Car is at the dyno shop! (5/6/2008 7:51:11 PM)
+1 I did a test to see how well the epoxy stayed in the holes between ports and after being left in front of the heater the imrc plates expanded so much that the epoxy fell out when Iggently poked it with a screwdriver so I did not fill those holes either . BTW I have no Idea what type of dyno it was, but I had only 269 rwhp before the tune so I got 13rwhp. : )
