Tim at mr norms is retuning the challenger this week in preperation for mopar nats. Here are the current numbers.

911rwhp @ 12psi
1365rwhp @ 24psi

Thats 37rwhp gained per psi. At that rate, he will eclipse the 1500rwhp he made last time at 30psi. Not sure what tomorrow will bring, but i voted to keep it there and not risk blowing a head gasket. Anyhow, i will post updates tomorrow if there are any otherwise i hope to have track results this weekend.

For those that dont know, this is a twin turbo challenger with our 406 longblock in it. Turbos are 76mm and shifting occurs at 7500rpm. I will post pics and more details tomorrow.

What fun is it if you aren't pushing it? You're only talking about a head gasket. I think it would be pretty awesome to see some 8's.

That's just insane. So this is the car putting out all that HP I read about! What changes were made to get that extra HP since the last time tuning was done?

Is that a sleeved engine?

Harrison, I believe its a Darton Sleeve 406.

And congrats again Andy, those are some serious freaking numbers. I can't wait to see what it does on high PSI! First challenger in the 8s?!

The sleeved motors are nice but a pain in the @$$ to obtain. We have done 2 and we are supposed to be doing 2 more but I have been waiting 6 months for these last 2 to come in.

You know when your HP starts to approach your curb weight in kg, s4!t is getting serious.
