Pro .15 Vs. 2.5 Runtime

I was wondering what the difference between runtimes are with the Pro .15 and 2.5. Did you have to refill more often or what?

I used to have the stock .15 in my Tmaxx before I did the upgrade to the 2.5.
When I was still running the .15, my neighbor had the 2.5 and at the track, he used about 2 1/2 tanks to my 1.
I don't think he was tuned quite right at the time, but now that I'm running the 2.5, I would say you get about twice the runtime with the .15.

Thanks, that was exactly what I was looking for.

It's well worth it. Ditch the stock cooling head immediately and go for an ACNCM monster cooling head. The engine will maintain it's tune with the additional cooling. The stock head on the 2.5 is absolutely the pits. I don't know anyone at the track who still runs a stock head.
The increase in power between these two engines is amazing.

Can you like elaborate on the ACNCM for me?

ACNCM......American CNC Machining. Check their web site.
That head made a stubborn 2.5 run like a champ at 240.

If that didn't work as a link, copy and paste it. It's their cooling heads.
Great prices, SUPER heads.

Sweet, good price too! The freakin stock head for the Pro .15 is like $30...

Thanks for the info.
