Finally got my car to the tuner Friday for a tuning session, I'm very pleased with the results! The final numbers were 407 HP / 370 TQ in 90*+ weather. The low numbers on the chart were my bolt-on/tune baseline before the cam swap. How are the numbers comparing to other cam-only cars? It pulls so much harder now even with my 3.42 gears, I can't wait to change them to 4.11 or 4.30s/4.56s
Mods:
BTR Stage 4 cam
BTR .660 Springs
LS6 intake (stock)
TSP 1-7/8" headers + 3" Y pipe to a cutout
K&N FIPK
Sounds right on par with others. So you gained 46 hp with just the cam and re-tune?
Yes just a cam and a retune was all that changed. I'm sure in cooler weather a few more ponies will be found but I'm more interested in track results than a dyno #. I wonder how much more power can be had if I swap the ls6 for a fast 102/102.
Nice....now put a fast intake on it and pick up another 20whp.
I thought about it, but the dollar per HP on that is kind of poor in my opinion Maybe if I find a deal on a 102 combo I'd consider it.

I agree, I was surprised it made 360 with just headers/intake on that dyno. I can't wait to take it to the track! I trapped 115 with bolt ons so I'm hoping to be at least in the 120 range, maybe 125?
Nice numbers...Looks like all the power gains are above 5k. Which is normal for a big cam. Definitely going to need some gears to keep it in its power.
50 whp gain is not going to pick up 10mph. If you trapped 115 before you might hit 117-118 now. With a set of 4.30 gears, 120 is possible.

Yea that's damn good on that dyno and your mph is good too. Should run hard with that new cam.
I have a black ported fast 102 not much time on it. Gonna have it up for sale in a few weeks. Also have a new black NW 92TB. Pm me if your interested in either. We could meet up and save the shipping cost
Now I just need some tire and a rear with gears better than 3.42s It pulls really hard up top now compared to what it was. I ran the 115 on street tire at the track too lol.
What would really wake up the combo is a nice set of ported heads. Aftermarket castings would be best, but even a set of ported 243's or 799's would help a ton.

I wonder what the power would be like with heads and intake, I asked BTR what they would suggest when I bought the cam and they said TFS 220s and a 102/102. I bought this cam intending on doing heads and intake in the future so that's not off the table

Brian has told me that his hand worked TFS 220cc heads, port matched FAST 102mm intake/TB, and the cam you have will be right at 500 rwhp. Obviously it's going to depend on the dyno if the number is north of south of 500 rwhp. If it were me, I would opt for Brian's hand worked TFS 220's and port matched FAST 102.

Going to depend on how much you are willing to spend on the lifters and supporting valve train. That key element makes or breaks a setup...especially one like this that is going to need spun to 7-7200 rpm to stay up in the power.
