I guess you have never been in the dyno results section, there are PLENTY of ppl over the 450 mark (dynojet) with this set-up

I concour. I can do the search for you if you'd like as when I was looking for what combo I wanted for my Formula I found like half a dozen guys right off the bat with more than 450 RWHP with the MS3, 5.3l heads combo (dynojet). But also take into consideration that other supporting mods were all done, meaning most had FAST 90's, with FAST 90mm TB, UD pulley, bigger injectors, bigger fuel pump, full exhaust, ect. This is all the exact combo my Formula is getting (with the exception of I am getting a 92mm intake, and 92mm TB), and if I lay down anything less than 450 RWHP I am going to be

My results should be happening on June 29th, and I will be posting dyno vids, and dyno sheets for all to compare to, if interested.

What size injectors do you have with it. I know TSP calls for 36#ers, I am putting the same combo in my 99 and those #'s seem low for a MS3 with heads.

You can do 36# injectors and be just fine. I went with some SVO 42# injectors just for a little extra duty cycle. Either will work fine though.

i have 42lbs Lucas injectors on mine, the throttle body and intake are 85MM. Also, its the Professional products Tyhpoon intake, you can use the search on the site to find a huge thread about them. I'm not sure how they compare to the FAST...i do know its like $500 cheaper. If fast would only gain me 5 horse, i'll keep the 500 bucks and put it in the rear end : ) I also did the dyno with the stock pulley, i will getting a UD pulley on it for the next run...i'm sure...save gas and wear accessory parts 25% slower and get the HP out of the deal.

Those numbers are low my buddy put down 433rwhp with just the MS3-Fast 90 Intake & throtle body-85mm mass air-slp lid-Full Exhaust and his were threw a M6 also. and i have the same head/cam setup you do put with the fast 92 setup and im hoping for atleast 430rwhp threw an A4.

my headers are 1-5/8 and not 1-7/8, you think that hurts the power at all with a stock cube motor?

You headers not not really hurting you because they are not 1-7/8's! you have said that twice now lol. My Pacesetter headers are not 1-7/8's and 90% of other people's are not 1-7/8's you might gain 5 hp with 1-7/8's. You dont really need 1-7/8's headers unless you have more cubes and heads that flow more. My friend with AFR 205's and t2 cam with fast 90/90 put down 470whp and went from pacesetter to kook's 1-7/8s and only picked up 3whp and 4trq! He was pissed that he spend all that $ for 3whp

I guess the ms3 cam isnt doing as good with these head as the torquer 2 cam because m6 cars have been making 444-470whp with that setup! Here is a friend of mine i told what to get and he put down 441whp 39*trq with a a4 with 3600 stall unlocked on a mustang dyno! so add 20whp easy! I have put this setup on a few cars all made 440-470whp!

Just because the cam is bigger dosnt always make it better! I dont no why TSP told you MS3 over T2 cam

alot of peeps have been using the MS3 no probs, its still fine, just runs a bit rich still and now that i have a clutch its all good. Also, whenever i pull the motor in the future and stroke it to 383-427....if the cam is in good shape, reuse it should be no prob, considering how big it is...we'll see

1 3/4 headers will net you the best power for what you have. The only time you're gonna see any extra results from going to the 1 7/8 headers is if you are pushing 500+RWHP (most best results are actually past 600 RWHP and usually can be seen on blower and turbo cars).

The MS3 is bigger, and generally speaking will produce more max RWHP than the T2 cam will. FWIW, most people with the similar combo I am going with with the MS3 and 5.3 stage 2.5 heads (with the supporting mods) do on average of about 460 RWHP. Most T2 guys generally speaking put down less than that.

The T2 is more driver friendly though, and for most would be a better driver cam than the MS3. The MS3 also does better with nitrous.

i would love to try nitrous sometime, but i don't like the idea of my intake coming apart and i've heard alot of horror stories out there that makes me think twice.....

Car did 441 RWHP, and 402 RWTQ.

Good numbers, looks like you would be better off shifting at 6500-6600 rpms instead of 6900

Also just so everyone knows those numbers are in "STD" it will be a tad lower when read in "SAE" corrected numbers

CALL911: WOW! I have the this same H/C combo with all boltons/A4 and can't wait to see what kinda #'s it puts down! I do however care more about track times than dyno #'s!

FWIW on a dynomite dyno
i put down 457rwhp the next day after the tuning was a little farther along. the posted dyno sheet was the first pull we did. PRC can easily make more than 420. i was told by the shop that the dyno they use reads similiar to a mustang rather than a dj. our mods are obviously slightly different.
