Ported manifold gain or no gain
Well im wondering if a ported manifold will help me out or not its for a 2012 bolton denali dont have planned to cam it or add a converter just regular boltons...going to order a ls3 90mm tb and have that ported too that im doing forsure but not sure with the manifold..any help is greatly apreciated
|
Peak performance does a radical port that is supposed to add 20-30hp. Not really sure how much you would have to do to get that done.
|
^^ thanks... Bump anyone done a ported manifold on a non cammed truck
|
I got a port truck fast manifold from peaks but still have not started my truck yet hopefully i will fire it up this weekend and I will post
|
their thread on LS1tech
Peak Performance Radical Port I've considered them as well, for the gains they claim and price it just seems better then the FAST intake, plus I've been seeing nothing but drivability issues lately on fast intakes basically for $600 you can have a ported intake and ported TB for basically half the cost of the fast LSXRT |
ill look for then hoepfully i get good gains with the ported truck manifold and ported 90mm tb

^^ did u loose any lowend torque? And thanks for the reply when your ready to sell pm me a price
|
Probably lost some, but compared to a a 4.8 or 5.3 it probably seems like nothing haha. I agree with you the fast are way to over priced for the money.
Question, not trying to thread jack! Which is better, the intake ports to be larger than head runners, or head runners to be larger than intake ports? I ask this b/c I'm about to pull the trigger on some ported 243 heads and this thread has me thinking a ported intake would complement the swap nicely. |
zero driveability issues, and zero low-end torque lost with the ported LSXRT (compared to OEM Gen 3 truck intake/tb on H/C stroker motor). Just TONS of top end power gained. It wasn't cheap though, $1500...
