price comparison on TPI intakes

theres several guys on this site running them now, theres several guys on several other sites running them also, EVERYONE so far has reported back that once they got it tuned correctly for the massive increase in airflow that in was a major increase in the engines abillity to make hp in the 4000rpm-6500rpm ranges
again look at the dyno results, vs a ported siamese aftermarket base, the CUSTOM STEALTH RAM pulls hard to over 6600rpm

if your interested heres a few links

link
edelbrock base
used TPI

vortec tpi base
compare that to a super ram at $1300 plus

or the mimi ram at $1250

SHOULD YOU SWAP TO A CUSTOM STEALTH RAM,IN A WORD,
YES, while it depends on your combo(gearing,stall speed,cam, cylinder heads,displacemen,ETC.
the HSR can potentially produce the best results for the money spent of all the currently available intakes, 60hp-90hp plus improvements have been recorded swapping from a stock highly restrictive TPI intake to a STEALTH RAM, yes it takes both the correct combo and tuning to use that big improvement in air flow but at least youll not have to worry about the intake restricting performance. my 11:1 cpr 383 corvette picked up in excess of 70hp with the swap, but the TPI intake was SEVERELY restricting my engines breathing, most of the improvement will be in the 4400rpm-6600rpm so a cam and cylinder heads that match that rpm range are a big help in getting the most from the intakes better air flow
read this info below carefully

keep in mind its the total COMBO, that matters, there are no MAGIC parts, MATCHING both THE ENGINE PARTS AND TRANS STALL/GEARING ARE MANDATORY for BEST RESULTS
if you need an extra 1"-1 3/8" hood clearance that the standard HOLLEY STEALTH RAM DOES NOT PROVIDE,(LIKE ON A CORVETTE!)
