Looks like you lost a bit of power below 2800 RPM's there Scheides

His car really did respond well to the HKS 280's and I see no reason not to get them on a stock turbo car if you have a decent tuner in your area.

 

thats great! i already have the ARP Head Stud installed, and would definitely get some spring & retainers..... i love lopey idle so thats not any of my concern great input guys i think im going for it,

 

PS-- you don't need springs/retainers with the HKS 280's, just keep the revs reasonable and you won't have a problem. Again, I have 35k miles on my setup, beaten on daily ARP's are good though

PPS- you don't need cam gears either

 

ive been running GSC S2s with my stock turbo and they're awesome. I lost a little spool (3800ish for 24*) but they're great.

 

3 of my friends had comp 280/280 and all 3 had no problems and all 3 made 380whp dyno jet and 1 was running a tial 50mm BOV no problems all 3 stock Ecu and the comp worked out really good in 1 of the car that got a BR3065 he ran 11.1 at 130mph+ 31psi you should have no problem with 280 on stock turbo

 

great info guys thanks.............

 

Check with 'Manny@toplevel'. He's running 280's on his stock turbo set-up. His car is on the list of 'fastest stock turbo cars in 08'.


You should be fine. Keep it under 8k.

 

I run comp 280's & trap 95.7 in the 1/8th on stock turbo

 

cosworth M2s on stock turbo, the car just seems to pull and pull

 

i plan on getting brian crower's 280, anyone make good off of them

 

c'mon people ... you cannot compare one manufacturer's "280" cam to another manufacturer's "280" cam. Different lift, different ramp rates, etc. It's comparing apples to oranges. HKS 280 cams will work with the stock turbo. Plenty of people have done so. As far as I've seen, setting them to +2/0 seems to work best - it did for me and Ted B and a few others...

I think or well I hope most of us know that, more than likely giving some feedback on different 280 cams. I mean they are giving the manufacturer's name followed by "280"

 

I just made 310hp and 310tq at cbrd on thursday with the cam gears at 0 on the stock turbo. this was with the brian crowers with the single valvspring upgrade, headstuds, ported im/tb, wiesco pistons and Manely I beem rods. 0 knock at 24psi

 

I would say Comp 280/280 or Tomei 280/280 hands down they are the best and you still have room to go bigger turbo or more boost you will have crazy topend with both

 

Did you change anything other than cams between the before and after run?
