I would go to a blower grind personally. I was told my N/A VT Stage 2's would cost me power with my blower. Your 270's should be close to the same cam. I really like my Crower Stage 2 blower grinds even on my car when it was N/A. I'm taking the car to get dyno tuned tomorrow so we'll really see how I like em . What type of blower are you running?

 

[jasonh_86]

Definately go with a blower cam.. Like as stated earlier, it can be costing you hp

IMO, i'd go with VT Stage 2 Blower cam.. or a custom grind from Tim @ MPH

your supposed to use a blower cam but i dont know how much of a hp difference it would actually make. having blower cams is costing me now but it should pay off in the end.

although i too like my blower grind even na now. not only that but its a stage 1 and i still make good rwhp and rwtq.

nah... you shouldnt swap.. then there would be no way I could outrun you hehe.

I would send MPH an email and see what they think about your setup. and when ya swap motors i need dem pistons lol

n/a cams are worse than the stock cams on a FI car. youd probably see an improvement just going back to stock, and a nice gain switching to FI cams like you need.

n/a cams are ground to allow for scavenging due to valve overlap. well now you have a blower which does that for you, but this scavenging is allowing some boost to make it straight out the cylinders during the scavenging.

are your comps the 270ah PI version? If so they are very good for blown cars...I did some asking around when i had my 262ah's and most said it was ok to use the comp 262/270 ah on blown cars.

 

[01Steeda]

yeah he has a PI motor, and I know he understand the scaveging details,.. prolly just wondering if it was worth the money for the swap vs hp gained.

 

[trikeffex]

yea i understand how the scavengeing works,i was just wandering if you guys thought it would be worth the trouble to swap out the 270's for a pair of blower cams.i've already put my 3" reichard racing ultra grip blower pulley on and an alky injection kit is being put on the car as we speak.i'm thinking of either doing an intake manifold next or maybe a set of p&p heads.
you can never beat me spike so just face the facts....lol.....jp

if you compare the specs on your comp 270's you will see they are more similar to some of the other leading 4.6 cam co's blower cams then NA versions. Now if your looking to squeeze every last HP out then go with a custom blower cam made for you...otherwise your 270's will work great.

yea i'm keeping the blower rick.i would have had to come out of pocket a good bit to swap to a turbo setup,and + i wouldn't really be home enough to enjoy it.
so i said to hell with it and put my smaller blower pulley on and got stephen to get my alky injection kit.
i should be flirting with the 11.5 range when i get the car back,but no rollcage for me.i'm about to redo my stereo system and do a few cosmetic changes to the car.
hit me up when ya get a chance man!
