what would you choose?

Holley Stealth Ram w/58mm TB
Accel Street Ram w/58mm TB (not super ram)
Accel Pro Ram

 

Pro-Ram

 

depends on the cubes

 

depends on cubes and motor specs.

which is the accel street ram again?

 

Engine is in sig. 355 ported out ZZ4 heads.

Street ram is a TPI with large tube runners, super ram base, and opened up plenum.

 

6000 rpm and less = HSR
6000 rpm and higher = street or pro if the heads can support the CFM

 

i agree with above!

oh i gottcha so the street ram is basically an upgrade TPI system lol thats why i wasnt gettin it..

HSR's flow well to 6000 and maybe a smidge above depending on ur application/cam. another one to look into would the the Mini ram but its $$$ but that thing will rev to 7000 no prob

 

Yep thats it.

I guess I will stick with my HSR for now since I will only spin to 6k.

 

oh yea also your 58mm TB is def too big. unless ur spinning 7000+ rpms ur not gona need that, u will lose throttle response/flow with it bc its way to big for a 355. 58mm TB flows over 1000cfm a 52mm will be better suited for your 355, it will def flow enough (900 cfm) and u will keep your velocities and your throttle response. a 48mm TB is good for 350-400hp.

im using a 58mm TB on my HSR 383 but thats because i have 30 extra cubes and spinning 5500-6000 and im barely in the range for a 58mm TB. u also didnt state what cam ur going with

 

If you already have the StealthRam stick with it. Changing intakes wan't do anything except change the power band,, add torque here,, loose horsepower there. Which would work best depends on what you want out of the application,,, and what stall speed and gears you want to run.

The StreetRam is WAY over priced considering you can get the FIRST Injections system right now in a group purchase over at corvetteforums.com for $850. The FIRST's HUGE runners and revised high-flowing base adds at least 300 rpm over the other LTR TPI systems out there and more power through out most of the rpm range. Power band would be off idle to about a 5800 rpm shift-point on your average performance built 355.

The StealthRam should be good for 2500 - 6500 on the same common performance 355 build.

The Pro-ram (single plane) won't give you much more RPM range than the StealthRam on what you've got. If you go bigger cubes,, and get serious,, single plane with a big T/B is the way to go.

58mm t/b is not be too big for your current 355 and StealthRam if you can add a little power shot and increase the fuel slightly in the chip,, compared to a 52mm.

 

If you are looking to buy a new intake set up, you have no real choice anymore. The Stealth Ram is the only one available. Accel has discontinued their injection systems. Your other (over priced) option is the TPIS Mini Ram. I have heard rumors that GM will be coming out with a "old" intake styled Ram Jet. I am waiting on official word before I make my decision. For me it is a little tougher because I don't want to cut my hood braces to put in a Stealth Ram...and I don't want to buy a taller hood either!!
