Dynamometer Results & Comparisons - Texas Speed 228R and LS6 Stage 1 Heads

Thanks to the great guys at Texas Speed I now have a respectable street driver :D Got a set of PRC Stage 1 LS6 heads (not milled), a TSP 228R 112LSA camshaft, and TSP pushrods. Guys at RPM Motorsports here in North Carolina handled the tuning. Really happy with the results too 416/377. Here is a list of accompanying mod's:

- P.I. 3200 converter (4L60E)
- Dynatech headers with CATs
- SLP Underdrive pulley
- LS6 intake
- Ported stock throttle body
- Stock MAF
- Air lid with K&N
- !EGR and !AIR
- Stock 3.23 rear with 17" TT2s and 315s
- Stock bottom end with 52k on the ODO

Congrats!! I saw your car at the shop and fell in LOVE with it!!! Very very nice!

that locked or unlocked converter? either way good power for the mods

Very nice, I'm suprised the HP curve isn't lower in RPMs with that 112LSA, maybe you have to go with a 110LSA to bring it back from the 6k-6.5k area?

Thanks Charles. Not sure if the converter was locked or not, forgot to ask. I don't think the Borla was open though. I dropped it off with the Borla block off plate installed. So it might have shown a little more power with that open.

Nice results. Any track times yet

No, this car won't see any track time. It is just my driver with a stock rear and stock trans. Don't want to start breaking things!

Wow! Great numbers, especially for an auto, with an LS6 intake, stock T/B, a reasonable cam, and only stage one heads... very impressive!

Solid numbers for an auto transmission! Glad to hear you are happy Todd! Looking forward to doing more business with you guys.

Congrats Todd! I bet it feels good to be back in the saddle!

Nice numbers for your setup, I like that 350 ft-lbs at 3300...looking forward to having RPM tune my GTO in a couple weeks!

Yeah Brian, 7 years without LS power...I am back in my comfort zone

Wow now I am really annoyed with my numbers LOL. Those are good damn numbers for an auto. I have the same heads but milled to 61cc and I'm making less power lol with a 225/229 .580/.590 114+4 LSA cam...........I'm thinking I need to change my cam now lol

Nice results man congrats:cheers:

Those are great numbers and with a little spray, that would be a wicked ass DD

It's a nice cam. I had a 228r 114lsa, with bolt ons (no UD pulley) with 3:73 and slp intake and PTC 3200 and netted 393/366 with stock 241's on a dynocom thru a 4l60.

Great numbers for sure with mild setup congrats man it will easily pull to 6800rpm :D
Graph looks very smooth too.

Very nice results. I always love to see new 228r combos, its a classic cam that makes great low end torque and carries its power throughout the upper rpm range. Congrats, I bet its a blast to drive, especially with that nice converter.

This!!! Want to see M6 numbers

Congrats man! Good numbers for stage 1 and auto!

Great numbers.

I am really, really considering getting back into the mod game.

That set-up has really piqued my interest.

That combo w/ M6 and 4.10s would be crazy fun!!!

Good job Reckless!!!

Cowpunk

Outstanding numbers through an A4 with cats to boot. Any other modification to the heads besides runners ported?

Made a few blasts yesterday and had a smile on my face when the Mustang in my mirror couldn't keep up. I think what I really need is a 3.73 rear and I will be there :D

Those are great numbers! How do the stage 1 heads stack up against the stage 2.5? I am planning on running this combo but with those kind of numbers I'm not sure if it's worth it to go with the stg. 2.5. Sorry to hijack, just thought I could grab some insight from someone who experienced it first hand

Can't say, maybe the TSP guys will chime in

Good results and my guess its locked.
