347/TEA 5.3/V.2 Polluter/Fast 92/A4/470rwhp/405rwtq
Had some pretty impressive results last night from what I consider a rather basic set-up with a V.2 Polluter cam.
Customer dropped his car off about 2-3 month ago with a knock in the bottom end. He had some internal engine damage and wanted us to R&R his stock bottom end for a forged Thomson Motorsports short block he picked up. Of course we would of loved to of built the engine, but he had already purchased this one so we decided to put our stamp on it in a few other ways.
Set-up is as follows:
-Forged 347 aluminum LS1
-Unknown forged pistons 3.903" diameter
-Unknown forged rods 6.125" length
-Stock stroke 3.622" crank
-TEA CNC ported 5.3 heads with 2.02" intake valves/1.57" exhaust valves 58.5cc chambers for 11.39:1 SCR and 8.4:1 DCR
-Tick Performance V.2 Polluter Camshaft 239/244 .624"/.595" 112+3
-PAC 1521 spring kit with Ti retainers(kind of old and tested 148 on the seat, but I think we're getting some valve float up top)
-LS7 lifters@.050" pre-load
-5/16" .080" wall push rods
-Fast 92mm intake manifold(un ported) with 90mm TB.
-Pacesetter 1x3/4" headers CORRECTION MADE AS I THOUGHT THEY WERE 1x7/8"!
-3" ORY with Borla XR1 muffler in I-pipe
-Car is equipped with a 3" cut-out, but the motor is non operational there for it was not used during the dyno pulls. Possibly another 10rwhp on the table for track use if it's needed.
-Yank 4400 stall converter which was flashing to 5100rpm un locked, it is a pretty loose converter, but it's going to run its butt off at the track like that!
-Stock 10 bolt with stock 3.23 rear gears
-Car was dyno'd on 275/50/15 Mickey Thompson Drag Radials with 23psi of air pressure. No pumped up tires or swapping tires for dyno tricks to get a higher number. The car was dyno'd just like it will run going down the track for the most real world tune possible.
-93 octane was used for the dyno pulls and 26* timing with a 12.6-12.8 AFR made maximum power.
With a set of "street tires" as in a set of 17's with a low profile tire this set-up would possibly make another 10-20rwhp over the drag wheels and tires it has on it now. That said, we want the dyno and tuning session to be as accurate as possible as to how the car will run at the track.
This car has already been 11.1@124 with a lot less power so it will be very interesting to see where all this new found power and torque will put him! I think we will see easy 10.70's out of this car and possibly even a mid 10 second pass if everything comes together right. This car still has stock shocks and springs on it so for it to run what it already has with a 1.48 60' is pretty good IMO! Hahaha!
Locked dyno graph:
Look at that torque curve! Flat as an arrow...
Un-locked dyno graph so everyone can see the losses associated with an unlocked pull versus a locked pull:

The loose converter really helps this car 60' and run like it already has with a lot less power with his old cam and compression with 64cc chambers(we verified chamber volume before milling).
If you'd like something similar, we are a dealer for TEA, Comp and can even build you a nice short block like this one! Makes worrying about fly-cutting and P to V a thing of the past with a big cam and compression.
We had over .100" on the intake and .140" on the exhaust with this set-up and the pistons it had.
It should run just as good as it looks and sounds as well!

That said, we thought that the converter was just really loose on the dyno causing some funny things to happen. When Jonathan started to street tune it, he commanded a WOT 2-3 shift of 6500rpm and 80mph. In the tune, the 2-3 shift is commanded and happens at 6550 and 81mph, but the car doesn't shift. Instead, it nails the rev limiter immediately. MPH never increases over 85mph when this happens.
Trans is slipping, badly in 3rd. I'm not one to speculate on power numbers too much, but if it was slipping in 3rd like that a day after we dyno tuned it, it had to of been slipping some on the dyno.
If it turns out to be the trans like we think it is, it may get built and then re-dyno tuned/street tuned.
Oh, I should say I know some will say, "Why only 6500rpm shift points"? Jonathan was just dialing it in and hadn't gotten to 7000rpm yet. The valve float it's getting is kind of unnerving, but I haven't heard back from the owner yet if he wants to try and put new springs on it while it's here, or enjoy it for a while and change them this winter during routine maintenance.

Martin the cam specs are 612/612 lift, 236/242 duration, LSA 113+4. Heads are a 61cc or 62cc. The rest of my mods are in my signature. What do you think this combo would make on your dyno if you don't mind my asking?

Guys, I didn't realize till this morning when I got to the shop and actually looked, but I lied about the headers. It does NOT have 1x7/8" on it, it has 1x3/4" Pacesetter's on it!!! Even more impressive still!

With the heads you have, probably 450rwhp/390rwtq-475rwhp/410rwtq

I think plan b needs to go into effect with the SNS S2 and switch to the SNS S3 cam. If I do not switch, I will always regret not doing so..LOL
Keep up the great work!

Martin, your killing me with all of these crazy numbers from your cams.. I no longer want to be left in the dust with a measly old 450 to 460 hp.....

I guess that settles that!
OR
We could go all out with a custom cam that would be out of this world...the choice is yours to make...

The performance some of the small cube Tick cars are making is insane....reliability is in the bottom end but the power is in the top end(Cam/Heads).
For reference, My stock cube LS2 with CNC'd 243's , headers , stock intake , stock TB ,and a 230/230 .629"/.629" cam did all it could do to break 420 rwhp and 390 rwtq.
My old 416 with a 234*/238* .650"/.650" with same headers,same 243's but with larger intake valve and port,and a FAST 102 and 90mm TB made 478 rwhp/475rwtq.
When it had issues and had to be taken to 418" to correct said issues, it made 490 rwhp and 477 rwtq with a 242*/249* .650".650" cam (Then Tick took over and got it where it is now with tuning ,TB and air intake swap).
My point is, to see a F'ing 347" with 5.3 heads make 470 rwhp is something else...

Almost forgot, it had 15" wheels and tires on it with 26.5" drag radials too...
