Just wondering what kind of gains you guys saw when yo udid the stealth, mini, or super ram swaps onto an L98. Any advice would be appreciated. Thanx

 

Ive run all 4 common intakes
ported tpi
super ram
mini ram
stealth ram

the ported tpi gained me about 20hp over the stock TPI.(power range, 1500-4500rpm

super ram gained me about 45hp over the stock TPI(power range 2000-5500rpm)

the mini ram ram gained me about 55hp over the stock TPI but lost torque below 5000rpm(power range about 5500-7500rpm)

the stealth ram gained me about 68-70hp average hp and close to 90hp at peak but lost torque below 4000rpm compared to the stock TPI intake (power range about 4000-6800rpm)

now keep in mind Ive got a full roller 383 11:1cpr with ported trickflow heads and full length headers, the stock TPI totally strangles that engines airflow above 4500rpm, so any intake system that flows more air lets the engine breath and produce better hp, the steath ram and the other intakes require a cam and headers to effectively use the better airflow

 

I agree, to see much of a gain over the stock tpi, your cam and heads must match the intake. Also, gears and stall as well. Obviously the higher you rev, the more HP you will see The tradeoff is streetability and low end TQ. There are many streetable combos out there for all the intakes listed.
