I believe those are the older grinds. Check here:

I'm running HKS 280s with stock cam gears on a BBK Lite, I see full boost by about 3k.

 

Wow really? Can you post logs or dyno charts showing that? That's awesome!

My HKS 280's improved spool-up on the stock 10.5 8 turbo by about 200-300rpms, when I switched from stock cams. Both on stock gears, straight up.

 

Now this is very strange! They have conflicting info on their site!

Look at this one: http://www.stikiller.com/product.php...cat=299&page=1

 

Hmmm? I am not arguing, Scheides. I just can't understand it. I had to advance my HKS 280/272's way over to the left to +2/0 to get my TME/10.5 to spool to about 22# by 2800 RPM.

 

That sounds pretty good, Steve. What is "full boost" presently, anyway? If you had adustable gears set at +1/-1, you could be seeing full boost by about 2700 RPM, although you would lose a bit of topend yank.

 

Full boost is currently 25psi on pump. I really dont need any faster spool than I already have considering my last DSM setup saw full boost around 5k.

 

thanks for all the quick replys, so switching to 280's may not feel a big difference just a badass idle lope s2's would be more suited for gains, talked to buschur a lil steered me away from gsc for some reason, if im looking for straight up power gains on stock valvetrain whats best bet now thinking gsc s2's ha and yes the red is ordered jsut waiting and it is ported and will be running 880's

 

What's not to understand? That's amazing spool! I saw 22psi @ 3400rpm on the stock cams, and 3200rpm on the HKS 280's. Nice linear power increase all the way up to 300whp@6000rpms, then up to 304whp @6800, then down to about 290whp@7600. These cams gained me 35whp peak and 50whp around 5500rpms, installed straight up on stock cam gears 0/0. I'm sure gears could have tweaked the powerband a bit, but I was so happy with them I couldn't be bothered.

All power figures are Dyno Dynamics, 1.0 CF.

While I'm blabbign on I might as well discuss the Kelford 272's. I installed mine with the gsc springs, and saw a loss of about 200-300rpms of spool-up. Sucks, but right inline with the stock cams, so not aweful. Midrange works out to be very very similar to the hks 280's (on the stock turbo remember). The reason I bought these cams is for the top end. Peak whp is almost unchanged, but I run E85 or alky injection, and peaking out at 360whp now with the hks 280's I'd peak at 6200rpm and loose 50whp by 7000, just sucked. With the kelford 272's, I now held power almost FLAT out to 7000rpms, then it dropped off similarly. Freaking sweet!

Now that I have a BBK, I'm super glad I went with the kelfords but always wonder how the HKS 280's would have run. The main reason I'm happy is because my top end is phenomenal, the kelfords with springs let me rev out to 8000+ and this thing really flies with alky injection

 

hm dont want to do springs since i'll be doing cams myself and not sure abut my confidence in springs too ha

 

Alky+BBK+Kelfords=Nasty, scheides!

 

8's have 9.5 turbo i have a 9 and its a 10.5 unless u upgraded to the 9 turbo.

 

but anyway.. lol i have a 9 and i have all bolt on mods ( not including turbo, injectors, cams) and i know mivec is wierd to work with and people havent seen that much hp gains with more agressive cams... but im obsessed with torque.. im tuned at 380 wheel but it doesnt pull as hard as id like from a roll. my friends told me not to get cams because its a waste of money for the amount of power but now im seeing tuners able to get over 22 whp with aftermarket mivec cams. Although i do not know if thats with an upgraded turbo or not. i do infact plan on upgrading my turbo but for now wondering if i should do cams to increase torque... btw my car is daily driven if that helps with any insights.

 

03-04 8s have a 9.8 hotside, 05s have the 10.5 hotside like the IX turbo. The compressor side is still smaller on all the VIIIs though.

 

i was told once by an old school DMS'er ,,,, o never be affraid of going with big cams 280's it would just help you on your top end

it seems like people are affrai of them just because driveability and iddle is nasty,,,, dont be affraid thats why we have these cars right,,,, otherwise we would just get a camry
