First try my FTI conv would make 10lbs on the brake, sent it back in and then it made 6-8lbs, now sending it back again to hold the power up top.

Well my boost controller is set to about 9 or 10 psi, so it might make more still!

Im guessing the car will spin with the old converter we got about 4 psi and cut a 1.37 60, so i will be using a 2 step along with it

Thanks chris

Thanks, Chris
In most FI applications, I'd take the Pro Flo XT over any other "off the shelf" intake. I would ditch my ported FAST90 in a second if I could fit it without cutting my **** all up.

What he is saying is that the converter is making boost because it is too loose. If you took that converter to the track, you'll find that you will blow right threw it up top and have poor MPH. As they tighten them up, it'll be harder to build boost but will work much better out the back.

no i run a vic jr port matched now, but my porter seems to think a sheet metal style will gain me some power over what i have.. last year at 3250lb and 317 heads and 370 cube on 20 psi car went 5.54 at 128. swaped to bigger 235 head now, thats why i was wondering about it..

Don't worry about it. Some poeple don't have a clue, that's how you test it. I've done it MANY times.

Thanks. I know that is the proper way to do it in the pits, and i have seen it done. Your not supposed to do it on the ground in case it lets go.


Thanks chris

I hold the foot brake pretty hard and make sure I have clear space in front of me. If the pits are too tight I'll go to a open area.

Agreed. Tbrake/2 step timing and fueling should be tested and correct before you get to the line.

Not much sounds cooler than a turbo on the brake.

It should sound better with the two step thrown in there as well

Chris
you have a temp sender in your converter?

exactly, its hard on the stator in the converter, that's not speculation that's fact. Plus you're cooking the fluid in the converter, I don't care what you THINK the fluid temp is in the cooler or return line, it's a lot higher in the converter.

see above, maybe my original post was a little harsh, but it's still not good practice

And you're the guy who "has a clue" and tests his transbrake in the pits with his car on the ground

So what's the difference between doing it in the pits vs on the line? I mean with the exception of all the spectators.

lol seriously?


you do realize how long some setups have to sit on the converter to spool right? look at some pulling truck vids with large singles once.....

Nothing. I've done it for years. I've never had a tans or converter fail and I check it every race day. Just jinxed myself, lol. To each his own, I wouldn't check it with anybody or thing in front of the car (obviously). I drive my car around the track to warm everything up and test it then. I would love to hear how you check it without using it.

Like I said, if that makes something fail we have bigger problems.
