421 cheetta pipes

[ryskie22]

am just wondering if anyone has ever tried t4 pipes or no any thing about them, they look just like a cpi but smaller, i have tried them on the dyno with my old setup and then tried cpi s and there was no peak horsepower difference, just reved to 10000 instead of falling of at 9000 wich is what the t4 s did. my old setup was a 350 bored .060 with 19 domes in a coolhead and boysen reeds and 33 pwks,at 6 degrees timing, and it ripped but always didnt seem like it would rev out, you had to shift it quikly. so now i have a 421 cub with boysen reeds and 35 pwks and 18cc big bore domes in the cool head with t4s. havent rode it just trying to figure out if cpi s on this setup would make more peak hosepower or just rev out more than the t4 s, nobody seems to no about the t4 s,any input would be appreciated

I had a set of T-4s with a 4mil short rod and 34 carbs and an aggeressive port job and they did not work well. They fell on there face at higher rpms. I went to t-5s and they worked ALOT better. My t-4s worked ok with a stock stroke crank but t-5s work WAY better. CPIs would work the best for inframes.

thanks guys for the replies, i bought some cpi s tonight and will try the t4 s and the cpi s on the dyno to see what the difference is, it will be interesting. plan on dynoing this thing in the next 2 to 3 weeks, i will post what happens.
