whats the average h/p that would hold up to the punishment between these 2...
whoops forgot to mention its the 4l80e
sorry hehe

 

would help if you stated 60e or 80e.

 

80e sorry

 

I have the level 4 and it is still going strong after a year of spraying it with a 200 shot and 402. I haven't dynoed but I assume I'm past 600hp.

 

What are you hp #'s? I feel that after 600 rwhp a level 4 is a good choice. I personally do not recommend level 3 builds because the level 4 is a much better piece for the money. Vince

 

What kind of power are you planning? I'd assume the level 3 would be good to 600 or better easily and the 4 would be 700+

My level 5 65E has been over 500rwhp without so much as a flinch. And mine is an older unit, they've had upgrades since then.

 

i dont kno but probably close to 500 all motor and spray probably 750 .....

 

I would look at the level 4 with the NOS you are planning on using. Vince
