Comp 270's ok with boost?

Willy Mo · January 18th, 2010, 01:20 AM

I already have comp 270's and was wondering how well they work with some boost.

mrbigjeep · January 18th, 2010, 01:26 AM

i know a guy that ran them with his 70mm turbo and he didn't hit full boost till 4k or higher...i mean they will work but they definitely aren't the best thing for a boosted motor. i mean they are a n/a cam.

stock cams would hit full boost around 3500-3800

Willy Mo · January 18th, 2010, 01:29 AM

well i have yet to install the cams.. waiting on other parts and do the install all at the same time.. but am goin with boost eventually

mrbigjeep · January 18th, 2010, 01:50 AM

they will be ok...but not the best choice...i wouldn't doubt it if you regret it once its time for boost

mounder27 · January 18th, 2010, 01:54 AM

They will work fine for supercharged apps, now turbo is a different story all together, the cams need to release more exhaust sooner to be reach peak efficentcy for the turbo to spool up

Willy Mo · January 18th, 2010, 01:54 AM

well a turbo is what I will be going with

mrbigjeep · January 18th, 2010, 01:56 AM

even more reason not to get them lol...as the guy i was referring to has a 70mm turbo.

Willy Mo · January 18th, 2010, 02:02 AM

yeah i mean i have had the cams for a while but was waiting to install them. now i am pretty sure i am getting a T-66 turbo.

I8ACMRO · January 18th, 2010, 10:11 AM

Just get something like MMR Turbo cams. How much boost you lookin' to run?

Willy Mo · January 18th, 2010, 04:32 PM

well the bottom end is stock.. so until I beef it up it wont be to high.. 10# ish...

I will be picking up the turbo this weekend.... And what do you all think about fabricating some custome turbo headers?.. I found a site that has the tubing and even has the heagder flange for the 4.6

y2k02 · January 18th, 2010, 04:51 PM

I have the whole hotside, h-pipe and magnaflow magnapack exhaust for sell, but you would need two turbos.

I8ACMRO · January 18th, 2010, 05:44 PM

Get the MMR stage 1 Turbo cams or Stage 2 Turbo cams

Willy Mo · January 18th, 2010, 11:02 PM

yeah i guess I will be selling my brand new comp 270's.. and will be looking at some turbo cams..

but what about the custom turbo headers idea? think its worth it? or should I use the stock manifolds?

mrbigjeep · January 18th, 2010, 11:08 PM

i would just use stock manifolds...you are gonna have all the horsepower your stock shortblock can take anyway even with the stock manifolds...

and if you get a built motor you can just throw a set on then if you want when everything is out and apart...

JMO

i dunno about a 66mm but on 10lbs and a 70mm i know most guys are hitting the limit of what you would wanna push the shortblock to. and thats on stock motor

dude on here has 70mm and hit 400 on 8lbs...and other dude i referred to earlier hit 425 on 8lbs with the comp 270's.

Willy Mo · January 18th, 2010, 11:12 PM

well then itwill be a max of 8lbs.. or what ever is close to 400whp.. until a built bottom end goes in..

and its a Turbonetics T-66, Q trim, A/R 1.00, and is rated to 900hp

mrbigjeep · January 18th, 2010, 11:15 PM

8lbs would probably put you very close to 400...like right on. unless you need more boost with a smaller turbo...not sure. just sharing what i have found about the 70mm..

anyway, good luck

Willy Mo · January 18th, 2010, 11:18 PM

thanks... anyone know where I can buy a good t3/t4 flange to weld the hot side piping to?

2000ZincGT · January 18th, 2010, 11:45 PM

ebay

Willy Mo · January 18th, 2010, 11:48 PM

well I found this site
Merge Collectors True Merge Collectors

could get mostof the hot sideparts from here.. fairly reasonably.. But another question would be.. better to gowith a blow through MAF?
