BTR Stage 4 Cam Cold Start | LS1 | Brian Tooley Racing

Cold start on a LS1 with a Brian Tooley Racing BTR Stage 4 Cam. The idle is good and cam has a nice aggressive sound. Exhaust is longtube headers, high flow cats and straight pipes. 1998 Trans Am WS6.

Small blocks with nasty cams are awesome.

LS Chop is crazy 🤩

[@MattonCars]

Sounds great! Tons of chop. A bit choppier than my summit stage 2

[@DimeDimovski]

That idle is enough to wake up the dead 🔥

[@sergeantzoomie]

@@DimeDimovski it's definitely loud! Haha

I've got the BTR stage 3 cam with ls6 intake, heads, and long tubes but I'm only making 400 at the wheels even with the ls6 heads. It's tuned but I still have trouble sometimes keeping it idling especially when reversing.

[@sergeantzoomie]

@@alexhanson4101 I haven't had mine dynoed since I've owned it, but it was making close to 400 whp according to the dyno sheet I got with the car. Mine idles great but it surges and bucks when taking off from a stop or stop and go traffic. You have to rev it higher to overcome that. It can be a handful to drive in heavy traffic. I'm going to do a video on big cam drivability soon lol. I have stock heads too. Hopefully one day I'm gonna do a complete rebuild and boost it.

[@alexhanson4101]

@@sergeantzoomie I'm just impressed you were making 400 with the stock heads. I didn't realize the stage 4 cam with stock heads would put down the same whp as a stage 3 cam with ls6 heads. I definitely need to rev it a lot, I can only imagine the stage 4 being even more so. Sounds awesome!

[@sergeantzoomie]

@@alexhanson4101 yes, that 400 is just a rough estimate on my part. It made 373 hp to the wheels before the ls6 intake and holley fuel rail (not sure that would help much hp.) I need to dyno tune it again. That ls6 intake after the tune probably intensify the running rich problem.

[@sergeantzoomie]

@@alexhanson4101 the EST Dynojet HP was 428 on that same dyno sheet. Idk which is truly right. 428 or 373 whp..lol

[@CammedCorvette]

1) get a Fast 92 or 102 intake manifold 2) get a ls2 Throttle body 3) bigger injectors from FIC 4) better tune

[@htownzx21]

Shooo!!!

[@macc4]

You running upgraded valve springs, rods ect? Also if auto what stall converter you running?

[@sergeantzoomie]

@@macc4 the cam was already in the car when I bought it. The guy I bought it from said it had upgraded springs. I'm not sure about push rods. The car is a manual also.

[@zGraph]

what kind of power did this thing make?

[@sergeantzoomie]

@@zGraph it's right around 400 to the tire right now. It has cam, intake, tune, headers. I plan on doing heads one day and maybe rebuilding the bottom end and boost it too.

[@zGraph]

@@sergeantzoomie hell yeah dude. i’ve got an 02. just ordered the BTR stage 4 for it. gunna pull the k member and swap all my tubular stuff and 4L80 in and rebuild the motor. badass build btw

[@sergeantzoomie]

@@zGraph that sounds like it's gonna be a nice build as well! The stage 4 is nice. On bottom end power it's a bit sluggish, but it pulls on top end almost like a powerband. It really opens up and pulls in the upper end of the rpms.(I have 4:10 gears too) I bought the car with the cam already in it. I would like to take the car and get it re-tuned. That big cam overlap definitely makes the exhaust fumes smell a bit rich..haha

[@richardpetuck5760]

What exhaust you running also?

[@sergeantzoomie]

@@richardpetuck5760 longtube headers with bolt on cats and straight pipes.

[@sergeantzoomie]

@@richardpetuck5760 it is a Y pipe too, not true duals.

[@Jr1987Gt]

Badass have IG?

[@sergeantzoomie]

@@Jr1987Gt I have an IG but I just started it. I have one post so far lol. It's @sergeantzoomie though. instagram.com/sergeantzoomie?igsh=Zm1qdW1iczl5ZDVk
