LS2 CAM FOR TRICK FLOW 225 HEADS?......***HELP SpinMonster***
#41
Parts are ordered and the last box is scheduled to arrive this Friday. The parts were ordered from a forum vender and the install is scheduled to begin on December 20th at LG Motorsports.
Upon final build discussions, I decided to go with 11.5:1. The following parts are being installed:
236XFI/236XFI 114+2 cam
Trickflow 225s - milled to 64 cc
Cometic head gaskets - .040 (hopefully with no problem of leaking)
Yella Terra Ultralite Rockers
Ported FAST 102
NW 102mm throttle body
FAST 46# injectors
Snow Performance Stage 2 kit (meth injection)
Thank-you in advance to everyone for your input. I will post results once the install is complete. Hopefully I will be driving it home for Christmas!

Any updates????

I should have the final numbers in a few days. We had a few hick-ups with one of the parts that set us back. Tuning is underway and Anthony has started to add the meth.
As soon as I have the numbers I'll post the results.
Thanks for the interest & stay tuned.......

Care to mention of the hick-ups? Only reason I ask is to be informed incase it was a head issue or anything as I have gone ahead and ordered my whole setup (including the TW220 heads).

Spinmonster has developed Cams for the LS2 as well as the LS3. Yes his
Cams make power but he puts driving manners as a high priority. Having said that they are not max effort Cams. Getting to 500rwhp w a snappy
and flat torque curve with Trick Flows suggest Milling as well as a thinner gasket to get Compression. I had the heads milled to yield 11.8 CR . The
stock heads are 65cc and mine are 59.5cc. As it turned out I used Spins
earlier Cam with this setup and got to 500+ RWHP. Spin had recommended
the 230/234 Cam but I went with the proven 228/232. I could of had more HP/TQ if I went with the 230/234. Now I am considering the LSK 235 If I
dont go FI. Another Cam proven to get to 530RWHP is the G6X3 backed up by 10.5x @ 132. There is however some driveability problems with this one. Good luck with your goals, I'm sure Spin will help with more specifics.

Your current cam is a great power maker and if you like the way it runs, you will see right around 500rwhp. Keep in mind that 4.10's will lower the dyno reading on a dynojet by about 10-12rwhp.
I would swap heads first and see where you are at. The driveability of the existing cam will only improve if you bump compression.
Are you located near me? Colorado Springs.

Lg told me that a g6x3 needs flycut with trick flows. I think the guy i talked to didn't know what he was talking about. The tfs heads allow for the most ptv of any head so a g6x3 should fit without any issues. I know that people running tfs milled to 59cc with cams in the intake range of 236 and still clearing so I don't know why a g6x3 would have any issues with tfs heads. I think the guy i talked to at lg just wanted to get off the phone

I'm pretty sure you do have to fly cut it if you mill down to 59cc on the head. I'm going to have to double check my numbers (at home right now) when I get back in the office. We do more AFR heads than anything so the TrickFlow heads I don't recall off the top of my head, so I don't want to stick my foot in my mouth.

Waiting for the final results is driving me insane.

Should be able to have final numbers for you Monday sometime. Sorry if I bombed your email with dyno's on Friday but I knew you wanted to see updates as I went with it.

I have done a number of AFR/G5X3/FAST combo's that will put down 490-501 rwhp. AFR's typically make 10-20 more ft-lbs of torque in the 1500-3500 RPM range over the TF at least from what I have seen. PEAK numbers are pretty close to each other.
Depends on the setup if you would pick up with the G6X3 over the G5X3 cam and also where you want to pick up the power.

Substring. Interested in the results. Doing TF225s soon and was thinking about changing to a bigger cam as well.

The 225 is now the 230 V2 and it did have a good show on PatrickG's car but with the converter unlocked for the dyno, it had pretty weak Tq numbers. I was waiting to see results for the new head before recomending it to people.
I'll credit your findings.

A large number of people are following this thread and I can assure you that no one is more interested in progress than me.......Monday cannot come soon enough!

I dont design max effort cams. I refer others to tuner cams like the G6 if all they care about is dyno results. That may not fit what your looking for but many will look at the dyno results tomorrow and compare it to max effort high overlap cams as the only criteria.
Compression is key to low end TQ. This cam will run near 12:1 on pump gas without issue with meth being the safety factor raising octane. 1/2 a point in compression is about 8HP and 10Tq to the wheels at the peaks. The G6 cam closes the intake valve much sooner for boosting TQ with a given static compression but this comes at a price. I think your results will be about 485/435 which would be 495/445 with stock gears at 11.5 compression (lower than I think it should be--nearer 12:1). This represents a boost of about 25rwtq over your last cam while maintaining the exact same overlap, thus driving the same. If you bump compression it would get you in the 490's with tq in the 440 range. That would be 500/450 if it was a stock geared car. This hits your power goal with added TQ.

That surprises me because the AFR 225 was always an underacheiver in the low end TQ and Tony Mamo himself says that. The 205 was awesome but I only used it for one car.
The 225 is now the 230 V2 and it did have a good show on PatrickG's car but with the converter unlocked for the dyno, it had pretty weak Tq numbers. I was waiting to see results for the new head before recomending it to people.

Andrew (DSC3000) on the board has an LS2 with the G6X3/TF/FAST and he is throwing down 503/456 to the tire with a nitrous tune and no spray. I want to say we have hit a little higher on his car but that is close to what I remember his car making.
I have done a number of AFR/G5X3/FAST combo's that will put down 490-501 rwhp. AFR's typically make 10-20 more ft-lbs of torque in the 1500-3500 RPM range over the TF at least from what I have seen. PEAK numbers are pretty close to each other.

.024 would have been shaved off this TFS head on a straight cut to arrive at 61cc or .036 shaved to arrive at 59.5cc. In spite of the size
of the g6x3 I dont think he needed to flycut but would like to know
if He did. Anthony I wish you could clarify as it was a LGM build. Leon

Just a slight correction here ANDREW "DSP300" put 525RW to the tires. Thats quite a bit more than 503 which quite a few out there have achieved. He is running TFS 61CC / G6X3 and
.024 would have been shaved off this TFS head on a straight cut to arrive at 61cc or .036 shaved to arrive at 59.5cc.
