Curious what others have seen as far as MAX HP with the BTR 3 and all supporting mods. I was looking to maintain some fairly good drive-ability by sticking with this CAM.
Car currently has the following mods and put down 562whp/522wtq SAE:
AHP street ported stage 4 head pkg (resurfaced; no milling)
BTR stage 3 camshaft
Halltech MF 103 intake
FAST 102 manifold ported by Jeremy Formato
NW 102 TB
Stock injs
Kooks 1 7/8" LT's w/ catted midpipe
Burns axle-back exhaust
The mods that I will be installing shortly are:
ID 850 injectors
ARH 2" LT's w/ catless midpipe
MAMO ported MSD intake
Advanced Induction CNC'd heads milled .030-.040 to bump up the compression a bit
AT THIS TIME I do not "plan" to do flex fuel but I've been known to change my mind
Down here in San Antonio FBO BTR 3 cars lay down something like 625whp and 550wtq on e85. That dyno reads a little higher than most (so people say).
I don't have the most optimal setup but I made 580whp/545wtq just recently.
My mods are:
LPE ported heads
.050" mill
TSP 1-7/8" headers
3" x-pipe
BTR 3
Mamo MSD
NW102
Halltech 103
ID1000s
Flex Fuel
The most noticeable difference was when I added the Mamo MSD. Really woke the car up. I just changed out the Halltech for a Vararam and it feels a little stronger (SOTP).
Curious to see what you pick up with the change in parts. That's the route I am thinking of going. ARH 2" headers and AI heads.
ID 850 injectors
ARH 2" LT's w/ catless midpipe
MAMO ported MSD intake
Advanced Induction CNC'd heads milled .030-.040 to bump up the compression a bit
Headers 5-10 hp
MSD 10-15 hp
Heads 10-15 hp
Rough estimate of what you may gain potentially. Really interested in seeing your results. Good luck!
My cam is less aggressive then the stg 3 with less overlap and I made 618rwhp on e85. Our dyno is very conservative also, often a heart breaker for most. I think you could get to 585-590 on pump and 605-610 on E85 with a healthy compression bump.
I think 95s power gain numbers are all a bit low. Those AI heads really shine and love to make power. The mamo MSD has shown 20+ time and time again, especially with good heads and decent size cam.
Wouldn't be surprised if you saw 630ish on a dynojet (assuming enough octane).
575 rwhp on 21st century's Dyno jet.
WCCH heads with cbc porting BTR 660 springs.Milled .010
LS7 lifters
Radial ported stock intake and ported TB
LG 1 7/8 coated super pro headers, no cats, LG x pipe, stock mufflers.
I made 625 SAE Smoothing 5 on a dyno jet on e85 w/ AI stock ported heads, BTR Stage 3, 2" ARH, Vararam, Mamo Ported MSD, 102 NW TB. I switched to a Stage IV BTR Cam and made 641 SAE Smoothing 5 same dyno, wheels, temp, etc. Mamo MSD is worth every penny if you are considering it.

whay mods do you have?
