This goes to show what a T-trim blower can do with the right EMS and a solid tune on a stock block 
91/100 Octane Mix, 13PSI, 3 more degrees of timing:
91 Octane, 13PSI, Conservative Street Tune:
As you can see this car makes awsome torque for a supercharged car (almost as much as some turbo setups)
Hope you enjoy the car Armando!

That makes it even more exciting Sam! I have pretty simple setup too so it shouldn't take too much more for you to get me to that point also! BTW, what pulley did you use?? And if you did add a meth injection system, could you get even more power without compromising the stock block??

wow really nice!
so I take it belt slippage wasn't a problem then from how clean the dyno looks except the tq does start to drop off up top. It might be possible to hit the 500whp mark if it stayed at 400tq at redline
so 3 degrees of timing made like a 30 tq difference
What's interesting to me is when I compare these dynos to my car, this setup made up to 30 more tq than my car between 5000-6000 rpms, while I made up to 25 more tq below 4500 rpms, then again it was 20 degrees colder when I was dynoing
That looks like the stock 3.33 pulley since there's no lettering on the front so that's interesting to note compared to the stock blower with the 3.33 pulley - instant 90-100 hp by switching blowers
What sort of exhaust/cats/headers is this car running?
This actually gives me hope of switching to a T-trim blower someday. Next time I come in, I'd like to get that extra pulley added to my car
nice job! turned out great!
GTM definitely knows vortechs

Sentry - nice to have your observations - just curious why everyone doesn't pick a T-trim blower from the start?
Also wondering about the use of RC injectors vs. others...
Great job Sam, no question!

The T trim is 1200 + shipping + old blower and it is more likely to blow your motor up if your stock bottom. U can make similar power with the stock blower and 2.87 pulley and it will only cost u 70 dollars compare to 1200 due to buying a new pulley. 1 thing I dont get is why is the pw dropping up top? I thought u would keep on building more pw as u reach redline. At least that's how it is on mine unless it was slipping at the end.

Great job Sam .
Diesel..Looks like a really nice set up !
Sam could you post the chart with the boost on it ? Wanting to see where you hit the 13psi at . WHat serp pulley do you have on ? looks like a 3.12 or 2.87
Sentry......I had thought you said SEVERAL times that you thought the T-Trim was a waist ? We had a long debate about it...REMEMBER ? And now you're talking about going to it ...lol

booger,
...and I thought I remember you saying my dyno was over inflated or that aggressive timing couldn't possibly make my dyno as high as it was? Clearly this shows 3 degrees = 30 tq if you can prevent detonation
...and I thought I remember hearing nothing but the T-trim slipping the belts with the stock belt design. Up until now you and Dsport were the only ones doing the T-trim and I haven't been impressed with the belt slipping or breaking issues you guys have had. But if it can work with the serpentine belt setup without slipping at moderate boost levels, then maybe it's viable for a little extra power. I don't think I'd want 16-20psi like you've been trying to deal with though. That just seems like the point of diminishing returns with hotter air, but what do I know
This has been the 1st worthwhile T-trim dyno I've seen. Dsport's car had pathetic low end power with only 50 more tq than mine above 5000 rpms considering the psi level, cog belt system, and built engine etc was so beyond my setup and way more expensive. The only dyno I've ever seen you post was a low-res blurry mustang dyno from like 2 years ago and then read about you complaining about the belt slipping so much that you had to back off the T-trim blower to where you were making comparable power to an overdriven stock blower. So yeah I did question whether moving to a T-trim was even worth it considering how far the stock blower can be overdriven.
All I said was this setup gave me hope about going to the T-trim someday. We still have yet to know if a higher whp setup with the T-trim will provide good results and not slip too much with a modified serpentine belt setup. I'd rather have 450whp done right with no slipping than 500whp with the belt slipping like crazy. To my knowledge, GTM also makes a 34 tooth cog pulley for an additional 20whp or so. My plan is still to get a GTM stroked built long block with headwork and near stock compression combined with the 34 tooth cog pulley with my 2.87 pulley on the stock blower. Then someday if I kill my blower, I may decide to go to a T-trim instead of paying to get my stock blower fixed and probably use a 3.33 or 3.12 pulley with it. But I'll only switch if it's viable with minimal belt slippage. And I'd probably switch my final drive or transmission gearing
Sam obviously knows what he's doing and this setup is an interesting result considering it's on a serpentine belt setup and it made good power all over the powerband and not just briefly up high while sacrificing low end power.
I'd be curious to see a boost chart too. Considering this car doesn't have cams and we don't yet know what sort of exhaust/cats/headers it has and the weather being 20 degrees hotter then when I dynoed @11psi, I'm not too surprised about it peaking at 13 psi
BTW here's a comparison chart of my car and deisel's on our 96 and 91 octane maps. I'm guessing that my lower psi setup with water/meth injection is probably a little bit safer on the stock block, but you just never know

Nice. Best power I've seen on a stock block blower. Certainly impressive, lets hope it lasts!
What's up with the headlights on that car. In every pick my eyes kept wandering back to them. Looks like a bunch of yellow overspray and pinstripes on them...

Im only replying to you once . I dont want to take away from Sam's and Deisel's Thread about his car . And I will not go into my setup as you have about yours...in great detail in your 12 inch post . And you continuely get my setup and whats going on with it wrong . And your the one that said you thought it was a waist and now have changed your mind .
With a T-trim , you will reach 13psi before 6800rpm's unless you change out the blower pulley [ bigger ] Serp pulley 3.33 would be the biggest I believe , and or the jackshaft pulley [ smaller ] in this case as not to make as much boost . So I see by the pics that it is either the 2.87 or the 3.13 pulley on the serp side . If he wanted to reduce the boost to peak at redline or have it reach 13psi at redline a smaller jackshaft or larger blower pulley would be in order .
This is why I asked Sam to post a graph showing the boost level and whp level . If the boost reached 13psi before redline . The serp belt is slipping from where it reached 13psi to redline . Just exactly as mine did . I absolutely had no problems what so ever running it like that . And on a stock block , it will be great running like that . I just wanted to take advantage of my built block and thats why I looked for ways to build boost to redline .
So if Sam or Deisel could inform us on this question of when the blower reaches 13psi we would be able to tell if the belt is slipping or not....no biggy .

Booger, I haven't really changed my mind about the T-trim. I said it gives me hope about switching to a T-trim down the road.
It's more like I'm closer to "sitting on the fence" now that the T-trim has worked out for 455whp. That doesn't necessarily mean it'll work well for higher whp applications since we don't know yet how the belt slippage will work out at higher levels with a modified serpentine belt. I'm very curious how the TIMROD belt setup, the extra pulley I have added, along with Sam's new pulley added will work out for higher whp and countering belt slippage at whp levels beyond what I'm making
until we find anything out, I can't say I'm all for the T-trim or not.
Up until now I've thought of it as a waste of money (not "waist") when an overdriven stock blower has pretty much done just as well
