has anyone here gotten around 250 or 300 hp without doing a mass air conversion and the engine run good at idle? if so how, Id like to hear suggestions

 

im guessing im around 250hp 260 on a cold day. ive got the block and heads shaved, edelbrock preformer intake manifold, k&n, long tube headers 2.5 inch into an xpipe and summit welded mufflers(sneaks up on people). numbers may be off but itll beat my buddies 2012 hyundi genesis 2.0t rspec by 2 lengths through the 1/4 and ive beatin a supercharged harley f150.

 

All with the speed density system? and it runs good?

 

yep. i get about 20-22mpg on the highway if i keep it at 65. but she runs great. looking at getting some heads soon. gona try to break 300 at the crank

 

wow what type of transmission behind it thats very good numbers

 

E4OD. with a mild shift kit. truck is 2 wheel drive short bed single cab. weighs right at 4000lbs

 

I'm making around 280-300 at wheels..

5.0 .030 over flat tops
Comp cam XE264HR-14
Trick flow track heat heads
Scorpion 1.72 roller rockers
Ported truck intake
Hedman headers


Runs really good, has a slight surge once in a while.. But survivable..

I drive it everyday..
