st5 takes headwork right? and bigger springs and chain, Me personally Id do the St2 not as big which I would think would be less of a headache to get dialed in than the st5. IIRC the st2 isn't that much different than the xp cam as far as specs, could be wrong havnt looked at them specs side by side in a while.

**SnowFlake** · 01-13-2014

I'm dialing it in and I want him to go as big as possible.

**231FUN** · 01-13-2014

Don't bother with an st2 if you already have an xp unless you hurt the xp with your timing chain incident that is and want to stay with a smaller cam, the specs are pretty close to identical between the xp and st2 if you look at them. I'd go with the st5 if it was me buying and considering your options.

**danomite02** · 01-13-2014

nah the xp is fine(as in not damaged when the chain snapped) Just weighing my options.

ST5. Go big or go home. You've already twincharged the car, why stop there?

**darkhorizon** · 01-13-2014

doesnt really make much of a difference. SPrings are a bigger deal.

im sorta with dark on this one....id bias towards a smaller duration cam and bias the build towards tq than top end power...cams dont make much difference for us up top with our horrible rod/stroke ratio and its effect of killing cylinder filling at high rpm. doesnt mater how you fart with valve events when the piston acceleration rate is exceeding the volume filling of the oem intake tract/ports/throat...id bet your pressure ratio really starts to rise.....almost retarded to try to shoot over 6500rpm. might as well put a honda 4 banger in a mining truck while your at running things outside their design envelope...

we made 540whp unlocked with an st1r (st1 with more lift) at 18psi and stock qwikported heads with 130's, 608fwhp and 575ftlbs with the tcc locked

shoot man **** the cam i just want a trans to hold together...thankfully i now have a l60e bellhousing to make an engine dyno adaptor for Opel up the street...delete the weak link lol

Dan.. there is a lot of good knowledge in the last two posts, as well as a lot of actual trial and error. Going as big as possible is an ego trip, not a good build plan. Many of the guys that keep things reasonable make amazing amount of power for the parts involved vs the biggest meanest parts available. You aren't the guy that is worried about putting a part in to say you have it, you're the guy that puts in low cost, easy availability and then looks at the guys with the bigger parts etc in his rearview.
