MPH told me I'd lose 20% of my boost running 102600 Comp cams.

 

Did I quote you? Ummmm NO.

 

And you were told you would gain 100rwhp from their cams, now weren't you?

MPH is a great company, great customer service and turn out great numbers. However throwing around numbers based on one specific application (ie. yours) and comparing it to others (stock engine with mild boost) is irrational.

 

Then I apologize, it appeared to be directed towards my post.

 

Makes sense... I hate that marketing and crap everyone has to say they are better than everyone else... If a cam only makes 30 more RW then say it. I bought the CMS 2.5's and I'm hoping to gain 100rw from increasing the boost, Heads and Cams. Anything more is just icing.

 

Lol apology accepted.

Don't ever believe the hp numbers they claim. The cams I bought claimed up to 80 rwhp gain. I did heads and cams and gained 84 rwhp.

 

Every application is specific, which is why I always suggest custom ground cams to each persons' goals and desires. This whole "off the shelf" crap and the fact that the internet is a infestation of idiots compounds problems.

The Comp line is nothing great, but they do a decent job in both blower and N/A applications. They are older grinds, and advancements have been made these days in power ouput with different grinds. The Comp 268's/274's are a decent set of cams, but for the money spent anyone would be better off with something more specific. However, they do work and will make decent power (and NOT drop a lot of boost).

I installed a set of Comp 268's in a customers car that had forged shortblock and a Vortech S-Trim. Rather than chasing after horsepower numbers, he was looking to improve low-end/mid-range torque, which most mod motor owners would like to have more of. Those cams actually did a very good job of adding low end power, while still having enough in them to make ~460rwhp on very mild boost.

 

I can almost promise you'll gain 100 rwhp off heads, cams and 2 more lbs of boost. The 84 rwhp gain I got was with the same amount of boost.

 

well here is the story. back in early 06 i didnt really know anything about fords and i ran over a hitch laying in the road that put a hole in the bottom of my motor and i was just going to do cams and bolt ons and stuff like that so once the cams were ordered i found out the insurance company gave me enough money to get the vortech... so i called comp and asked them if these cams would work with a blower and they said a custom grind would work a lil better but they will work just fine with a blower so i kept them. and when i get everything running i was seeing 4-5 psi and i thought my blower was messed up so i called vortech and told them that i had cams and stage one port on my heads and he said your motor is flowing better so thats why i have the boost drop. but then i intercooled it and put one size smaller pulley on there and now im getting 9psi and that is what the pulley is rated for.

and as for the rings i put rings that were for a blower in there and they were the same that were in there since the builder did know i was getting a blower but since he doesnt do anything unless he is told to he didnt change the rods... hints my dad didnt tell him to.

so if your saying my cams arent for a blower syxnerd then why am i making this good of power when a KB 2.1 gt with 9psi is making almost 80 less hp and 10 less tq(centrifugal aren't known for TQ #'s anyways)

i know there are better ones i could get but i had several people tell me that these cams would work and the more boost i have put it it the better numbers im getting. they should be better when i get more boost in there... after i finish the motor that is.

not saying your wrong and know numbers arent the thing that count... but when i race a pullied cobra that is making 450hp and 470tq and we run door to door i think the performance it pretty good and i have raced others that i have beat by a 1/2 to 1 1/2 cars with the same or more hp.

so lets get back on topic here. thanks

 

You could probably get a little more power out of a custom ground cam but it's not worth the money. Your car is making dam good power the way it is. The only modification I'd make is the rod change.
