Building a 408 with 11:1, 2.055/1.6, 238/242 115. This is through a built 4L60. Any predictions on HP through A4? Has PY3400 converter. I havent seen any 408 dyno graphs but I know they are making normally at least 490+

Also have LCA, relocation brackets, TQ Arm, SFC, Panhard and plan on hopefully 1.6 60' I am thinking car should run hopefully mid to low 11's on motor, if not high 10's with good conditions.

Motor is setup for spray but I think I will go for max NA results before I put the wet shot on it.

Any thoughts?

Thanks

 

Wont guess on HP, but if you are putting down 480+ through an auto you better be running high 10's and never mid 11's. You can get mid 11's out of a cam only auto that is setup right.

I know I made 410HP on a 100 shot with my stock motor way back and ran best of 11.51. So thats why I said with right conditions 10's...or **** maybe 10's all day long. Either way I gotta order my cage now..

 

Yeah go ahead and put the cage in so they dont kick you out when you run that 10.XX Be sure and let everyone know if you run 11.6 or something so I can come kick you in the ***.

 

You also need to get rid of that stall and get yourself a bigger one. Thats not going to cut it anymore with the new combo.

 

I know I was worried about that. Thing is, I basically just got it and waited forever to get it, as anyone who buys a yank verter knows it takes a while.

How much will this converter hurt? Wonder if i can get this one restalled to 4k? I will contact Mike @ Yank

xfactor only thing I can see being a prob running 10's is Im on a 4L60 and stock rear. But I know a lot of guys with A4 are in the 10's. We will see.

 

stock rear isn't as big of an issue with a4's....they don't crash down on the rear end as rough as the m6's. i'd def hit up yank and see if you can get the restall...see if they'll do it w/o using your one free restall credit since you had to wait so long

 

true..

 

Here is a quote from Mike @ Yank:
"that converter we be around 3800 behind a 408 and work well! it will be best is to try it first but a pt 4000 we be faster
mike"

He is basically saying this verter will act like a 3800 behind this motor...
