Friday, Nov. 25th I had three 3rd gear dyno pulls on a chassis dyno...

My stock baseline run the car put down 214.3hp @ 6408 rpms and 188.2tq @ 5200 rpms in Aug. 05'

The results of the 3 dyno pulls with intake and exhaust are 232.2hp @ 6379 rpms and 208.29tq @ 5089 rpms.

That is roughly 17.9hp and 20.9tq increase!! Which I think is very impressive with just an intake and exhaust!

I'm very satisfied with the way the car reponded to these simple mods!

I have a K&N Typhoon CAI and a Magnaflow 2.5" Cat-back exhaust installed.

All dyno sessions were done on a chassis dyno and all were 3rd gear pulls.

 

Nice numbers!

 

Very nice. I like how the peaks came a little earlier. Were the climate conditions the same or was it computer corrected?

 

impressive, cant wait til I get my catback

 

Hot stuff, I wish someone would dyno separately so we can see what % of that is the Exaust and what % is the intake.

 

but the weather is completely different you really dont know how much you got. not trying to be a hater but seems like everyone on here doesnt understand how a dyno works

 

I wonder how much im putting down with my Fujita and my 3.0 Inch AAP catback.

 

I asked about the climate. I think there are some shops with indoor dynos or at least there should be. That would solve the climate issues.

 

It doesnt matter. Hes posting his dynoresults, so WTF cares. I had this crap about oh you gotta take sea level, temps, the dyno etc. fine if we are comparing two different cars using 2 different dyno's, temps, area's etc then your argument makes sense. However hes showing us his, so whats the problem?

I guess they make such a difference some SS's make 120 at the wheels on one dyno, and 300 on the wheels on another dyno right? No...

Most of the dyno's are arround the same #'s and only differ a few HP.

Mustang dynos are usually 175-190

dynojets 210-230

stop picking on the little *****, compliment him and move on.

 

I believe they were computer corrected and the dyno was inside, but the climate conditions are diff. due to one session being in the summer and one late fall...

 

Thank you! Also, climate conditions can throw numbers off, but not by too much...

 

good numbers should have done it in 4th thoe

 

ya, 4th would be better but I like your results and I hope that the climate change did not affect what increases you saw.

How dose the car feel and sound know?

 

no you dont get it man, for all he knows that **** didnt do anything for the power, granted it prolly did but use some common sense. the car could possibly have dynoed that high with no mods now purely because of the temp change. to get an accurate gauge for how much the mods did for the car you would need to dyno it, change parts, and dyno again right away, that would tell you...

 

agreed, to get an almost 100% accurate difference.


I know arround here most of the time atleast season to season the temps really dont change all that much. 10 degree's isnt going to make a 15 HP difference, so you can still take it to be semi accurate. sure if he dynoed the first time at 115 degree temp and the second time at 33 degrees then there may be a marginal difference in HP. but if it was within 10-20 degree's the change would be negliable atleast IMO.

 

ok so what was the difference, was it the same dyn? just remember dynos dont run races

 

Dude he didnt say so you shouldnt be assuming and neither should I. I wish there was more then 1 dyno arround here, and I dont see why I would go to one dyno, and then 3 months later go to a completely different one and then post on a site about the differences. I cant speak for him, but common sense says he used the same dyno, same car, same loccation, only difference would be hte ambient temperature.....

 

jsut seems like people are so concerned about making horsepower, and not actually worried about going faster. and half the time they dont even know if they really are making more power. power isnt even what these cars need ITS TRACTION!!!

 

I agree with you to an extent. yes our car's need mad traction, from a dig. Our launches are horrible, and its all in the suspension/tires/etc. From a roll our cars are complete animals, but when we look at their 1/4 times we are disapointed. The reason is because of traction and 1st gear gearing etc. Once our cars are rolling the power will get put down good regardless, the only place we have problems is from a dig. I can live with that for now. Unfortautely theres not much of an aftermarket for our cars right now, but give it a few more months and IM sure it wont be any worse off then it is now.

yes you want to build a car that has the traction to handle the power. Too much of one and too little of the other is most definately a bad thing. Its nice to hear that you can get nice gains from an intake and exaust tho. I know in my SE-R I got about 2 WHP from an exaust and 4 WHP fron an intake.


so 6 vs 20+ is a really big difference, regardless of how you put it down.

 

Damn! What did I start...LOL

Ok, I asked about 4th gear pulls when I had my baseline run and they stated that they rather do 3rd gear pulls. That is besides the point the gains are there even if it is a 3rd gear pull. Both dyno sessions were done at the same place same dyno only difference was temperature which could cause somewhat of a difference. Yes, there are so many contributing factors, all I wanted to post is that I found that with an intake and exhaust on my SS/SC, I found decent hp/tq gains...Take it or leave it!

The car pulls alot stronger now. With the intake you can really hear the s/c scream and the exhaust is deep and mellow, not buzy...

 

good numbers.

 

nice numbers man

 

Whoa majority of the posters in this thread are from DE!

Didn't you originally get dyno'd at V2?

 

Yea, I had both dyno sessions at V2....

 

I just noticed your cobe is black... I thought it was blue.... damn, delaware=black cobalt ss majority
