: How much will a CoPilot help a stock Trans?

I was curious how much power the ATS CoPilot would withstand all by itself.

So starting with a new 2005 truck with a CoPilot (6300lb raceweight), I took it to the track with about 420rwhp (need to verify next week). The Verdict:

After 6 1/4mi passes it limped the trans in 5th gear. The 1-2, 2-3, 3-4 all clipped off sharp shifts with the CoPilot set on Drag Mode. But 5th gear never really held, not even one pass. The tach needle wandered between 2500-3000 during fifth gear.

It appears it doesn't do alot for the weakest link, 5th gear. It is probably best used as an enhancer for a properly built transmission.

Can't have my Hubby running around singing "I Limped it, I Limped it" :lol:

Good info McRat. I know people have asked how well a co-pilot can help a stock tranny hold more power. I guess we know now. What power adder were you using?

Mike,

I know for a fact that Big Blue is under the weather. Since that is "Kat's" truck, you might have nothing to worry about.

Oh, by the way Pat what is a Copilot, I remember hearing that term somewhere..

Used the PPE Hot with no lift pump. 420rwhp is just a guess at this point from the MPH it ran.

I can't wait. Shoul be a lot of fun.

I guess I can't say I'm surprised at what you used Pat. It will be interesting to see how it goes in July.
