How To Select The Correct Turbocharger/Torque Converter?

Goals, goals and goals. Without a goal it’s hard to pick out the proper combination. Not everyone needs a ten second turbo.

OP says he wants to run 10's. You and I know it's addictive. How fast is the Firechicken gonna go...

I must have missed that....

Just depends on how far in the 10s he wants to go.

My firechicken isn’t going to be fast, everyone knows you can’t go fast with a manual gearbox and a turbo!

Does anybody else just roll their eyes and turn off posts that have ''how do I run 10's''?

So is someone supposed to have a performance goal in mind, or not?

It is hard to know you are accomplishing anything without goals. A written goal is easier to attain in my opinion.

Am I incorrect in thinking that if a TSA car on 28psi through a Dutt Neck SLIC, runs in the 11's, I should be able to build a car that runs in the 10's with better heads, turbo, FMIC & no need to retain the stock appearance?

I don't see any mention of 10's from the OP. It slightly annoys me when people have an idea of a timeslip that they want to run because most hardly spend time at the track. Most guys who run 10's at the track aren't running that on the street. What I mean by the street is, they have a different tune as well as different tires/rims that they use at the track. My idea of a legit 10 second car is one that will do it without changing anything. Just get in it, and drive it. Instead of time slips, people should build recipes for potential HP and Tq numbers and RELIABILITY.

For how junk my car is, this 6262 and PTC 3k l/u combination is mind blowing. I wasn't expecting this turbo to spool as fast as it does on my stock engine...

I couldn't agree more and what it runs it runs.

Dan was running a CPT-66 and going low 10's.  He then switch to the 6766 and ran the 9's I believe.

Steve it seems to me you are trying to compare a race only car to a real street car.


 A real street car that drives to the track and puts the race cars on the trailer is what impresses me.

I understand that Steve, and I wasn't opposing anything you mentioned. I was just touching on what Earl mentioned as far as guys wanting to run a certain time in the qtr mile and it being annoying. As far as the OP is concerned, I was only saying that based on what had read with regards to turbo and TC combos, the combo I have "ideally" is too much but I have not sacrificed any drivability on the street with it. I think track times are cool, but I prefer dyno numbers only because I feel like the drivers of these cars are far less consistent than the dynos. As you mentioned, the weather plays a HUGE role as well as track prep and other things that are beyond our control. I'd rather have a car that was dyno tuned on the "safe" side so i could at least know theoretically what it "should" run as it sits; not pushing it to the limits like some do because they're chasing a number.
