lfp gt2-3, ls6 sping
pacesetters and 3.5" cutout

i put down 301/280 through a 14b and 35" tires with the converter unlocked on a mustang dyno.

 

221 221 558lift 114lsa, lts, flowmasters, cai, 60e-edge 3600, 4.10s, it made 316hp and 288tq on a mustang dyno 2ed gear pull unlocked. btw this is what i ran the 13.4 at 99 with.

 

when i dynod mine they got 368hp and 350 some of torque on a mustang dyno at xessive with my nex cam custom grind 224/228 and a 3000 multi disc pi converter and had 4.10's installed those are the only diffrent mods that i did than before and thats on my 5.3 engine

 

ls1 with patriot stage 2 heads ls6 intake full bolt on with 226/226 112+4 cam = 409hp 390 tq.

same setup with 231/239 111+2 cam = 429hp 390 tq.

since then ive added a ported fast 90mm, and kooks 1 7/8 stepped to 2" headers with a full mandrel bent 3" true dual setup. no dyno numbers yet but it feels ALOT better.

5.3 TR220 112+4, 60e TB stall, 3.73s, 3rd gear pull, 106* outside and it put down 335rwhp and 325rwtq

 

I am so disappointed in mine..... It has to be the manifolds holding it back mods in sig on 5.3 with asa cam only at 271/305 now...... hp tops out at 4600 then starts to drop so it has to be the manifolds choking it up!!! I'm saving my pennies now for the headers!!
