zzSIDEWINDERzz Posted December 6, 2016 Report Share Posted December 6, 2016 Hey guys, Thanks for letting me join. I am looking on some advice on Intake Manifolds. I'm wondering whether or not it would be worth it for me to swap manifolds. I figured this would be a good place to ask for advice. I will list my main mods and then list all of them at the end. I have a MMR Stroker (4.75) with the Boss 5.0 Block (Total 5.1L) in my 03 GT. It has Stage 3 Ported Trick Flow heads, Stage 3 MMR cams. I am limited to intake manifolds because of the Shaker system which has to mount in locations of that of a stock intake. I have a Professional Products Typhoon intake manifold that has been Stage 3 ported and polished that would work but I became weary of installing it because of the bad rap it has. I could also do the Victor Jr. but I don't want to loose low end power. I'm currently running the stock PI intake and was told to leave it in unless you are making some crazy horsepower. The car is N/A. Any advice? Would the horsepower gain be worth the swap?

Blackmage Posted December 8, 2016 Report Share Posted December 8, 2016 I guess ive never heard of PP intakes having a bad rap? I did a quick google search and saw some stuff on LS motors with the ports not matching up. Unless they have been known to just explode for some odd reason, i wouldn't see any reason not to run it.

zzSIDEWINDERzz Posted December 8, 2016 Author Report Share Posted December 8, 2016 They are known for leak issues and they are very cheaply made in China. You have to port them for them to be decent. I may try to sell it and get the Victor Jr. Thanks. Link to comment Share on other sites More sharing options...
ttocs Posted December 9, 2016 Report Share Posted December 9, 2016 PP is an entry level product imo. I had their 75 mm tb and always had problems with hanging idle until I got the idle adjuster. After I sold it the next person had the same issue. With everything you have in that motor I can't help bu think that its going to help it breath better.

zzSIDEWINDERzz Posted December 9, 2016 Author Report Share Posted December 9, 2016 Thanks. I think I will try to sell the PP and get the Edelbrock. My only concern with an intake swap is of course the loss of low end but the only way to get the absolute most out of the motor at this point would be to swap the intake. I ran out of time this year (winter showed up in Canada) to get it Dyno tuned. It hasn't been retuned yet after all the work that was done. Very curious to see how much HP it will make now.

RassCar Posted December 9, 2016 Report Share Posted December 9, 2016 I have a couple alternatives in mind to the Edelbrock. You could try to find a Bullitt intake, or get a Trickflow intake. Trickflow uses a similar design to the Bullitt but I don't know the finer details. Both should work very well on an NA engine without much loss of low end. Those would be my top choices for an NA 2V. I wouldn't go with the Edelbrock unless you plan to stay at 8k rpm. Link to comment Share on other sites More sharing options...
zzSIDEWINDERzz Posted December 9, 2016 Author Report Share Posted December 9, 2016 Thanks for the advice. The reason I have not gone with the Bullitt or the Trick Flow is because of my Shaker system. The Shaker scoop mounts to locations that only a stock intake provides. With the Bullitt or Trick Flow there would be nowhere to mount the Shaker brackets.

zzSIDEWINDERzz Posted December 9, 2016 Author Report Share Posted December 9, 2016 I basically have three options. Leave the stock PI. Install my Ported Professional Products Typoon (not sure if the increase would be worth it) or Get the Edelbrock which I think would work with the Shaker. Just not sure if the gains of swapping my intake would be worth the loss of low end. Link to comment Share on other sites More sharing options...
zzSIDEWINDERzz Posted December 9, 2016 Author Report Share Posted December 9, 2016 I guess I could ditch the Shaker and get a cowl hood. Then I could run the Trick Flow Intake. Link to comment Share on other sites More sharing options...
RassCar Posted December 9, 2016 Report Share Posted December 9, 2016 I know it's possible to mount the shaker to the hood, but I've never looked into it myself as I don't have one. Link to comment Share on other sites More sharing options...
ttocs Posted December 12, 2016 Report Share Posted December 12, 2016 how much of a loss of low end do you expect going from a stock to what ever the new one is? Link to comment Share on other sites More sharing options...
