which is better for a boosted application

a fast 90 or a carb'd with an elbow. if you can give your reasons why or no

trying to figure out which way i want to go

 

imo , the carb / spider intakes are superior to the car/stock/fast intakes just becasue the more even distribution of air. i think erik turbochargedberserker posted some info on intakes recently. not to mention most of the big dogs are running them with fi and parish's truck had some decent results. im sure erik will have the same. im going to be hitting the dyno with mine soon also.

 

yea i seen parish switched ot one but didnt know how much gain he saw. and i think i can do the carb'd for alot less then the fast 90. and if thats the case thats 2 birds with one stone. and which will probably be something i pick up then with enough info backing a carb'd intake

 

You won't see much of an improvement if any with the fast 90. Go with the carbed intake.

 

Fast 90s are known for busting at the seems also under high boost.

 

Really? I haven't seen that yet, I've read a lot about the FAST when I was debating between it and the Vic on Tech and never came accross that.

 

Yes, there have been reports of them blowing apart if you don't follow the "high boost" instructions from FAST (take it apart, epoxy all the seams).


get to go vic jr can be had for ~$700 including the elbow or down draft adaptor plate (what I use). I believe the FAST 90 total (rails, etc.) is closer to $1300.

 

quik, here's a couple of good comparo links;

May not have the exact answers as for boosted applications but have good info.

 

That would be a spendy misfortune!

 

Here's the sticky "hard data" link I posted.

You can see by the flow data how good these vic jrs are, and by the torque comparo that there is not much / no torque lost compared to other manifolds.
