ms4 and 408 with stg 1 243's guess on my numbers Ok so i had a spun rod bearing. I tried finding a good stock cube rebuild kit for cheap but couldn't so I decided STROKER. First i was looking at the 383 through texas speed. But then chris with CCperformance made me a great deal on an Erik Koenig built 408. I am runnig the MS4 on a 111.5 lsa with stage 1 ls6's from texas speed. I also have all of the basic bolt ons ported tb, lid, full exhaust with lt's, ud crank pulley but i have the stock ls6 intake. The engine will be right about at 10.8:1 cr and im running the stock 3.42 gears in my 10 bolt through an M6. I will be getting it tuned shortly what do you think I will put down on a md with a good tune? sorry for the length.

MD~450-460RWHP
Dynojet~480~RWHP
With a 90/90 setup you should clear 500~ on a dynojet
Mill the heads or run some cometics get the setup to 11.2-11.5 compression and the car should make 500 all day

Should look similar to the graph in the thread below after you get the FAST intake.

Maybe 470-480 with a fast 90/92 on an honest reading dynojet and about 440-450 on an honest reading Mustang Dyno. Can't really relate to anything else that has their numbers corrected to "read like a dynojet" on other brand dyno's.

That car made 500rwhp on a dyno dynamics which supposedly reads 10-15% lower than a dynojet. Not doubting the cars performance but too many people just see the number and overlook the fine details. Im sure those numbers were corrected to "read" like a dynojet but it still isn't a true accurate comparison IMO.

My car was dynoed on the same dyno as fifedogg.
I wouldn't say the numbers my low

You're already missing the crucial FAST intake.
Your exhaust might be less than ideal as well.
If you had all the UPgraded bolt-ons, you would see WELL in excess of 5xx rwhp and a LOT of torque

You are free to start a new thread after you have some results. This section is for dyno results and comparisons, not guessing games. That's better suited for the Gen 3 internal section.
