TFS Track Heat VS Cobra intake , dyno #s and video are here

[Slow5.0]

Ernan, I dyno'd my car before and after the TKO swap and I lost now HP and only 2ftlbs of TQ. It did slow me down a solid 2 tenths at the track though, I still can not explain that one though.

Nice numbers regardless!

Well i don't know how much i loston mine, buthave to be something , nothing crazy,justa few HP/TQ

Its not like i braging about lost , i just sayin thereis lost buti don't know how much because i neverhad chance to find out because i broke T5 just before i was going on dyno to test new intake

The conditions from various things can contribute to the difference at the track...from dyno time to dyno time and track time to track time.

Cool thread! Thanks for posting up the numbers.

I hope to dyno my car soon to compare my Systemax intake to my Performer. I know I lost a little down low, and gained some up top, just want to quantify it. I really had to richen my car up past 5000rpm with the Systemax intake.

and the TFS is comparible to the eldelbrock performer intake right?

streetheat is closer to the performer, trackheat is closer to the performer RPM

Could you share your tweecer file with me? I would like to see your timing/fuel tables. Also which base eec file are you using? Cobra or GT?

inertia of the heavier power train?

Its not i don't wanna share with you , its we have different mods and my timing is aggressive

no prob. I didn't plan on using the file. I just wanted to see how you went about it is all. I will have a slightly different combo in that I will be using a stock cam and plan on going turbo.
what did your total timing end up at and what was your a/f.

If I recall correctly, the tko's are around 30lbs. heavier than a standard t-5.

Exactly 30lbs, when i shipped T5 back to place i bought from it was 75lbs , when i send back demaged TKO500 it was 105lbs ,and all thoseweight is mostly inside of tranny (gears)
