Stage 2 sc build has begun

tiller · 01-11-2016, 08:15 PM

As you can tell iam a boost newbie,usually just build na motors or race bikes but iam learning

Anybody here talked with guys aypt specialty z lately?trying to get ahold of somebody to discuss ecutek tuning and support

After talking with gamma about the pulley sizes and I was told the 92mm pulley is 9-10 lbs at sea level ......so depending on altitude would affect the boost pressure

Just remember you have a stillen udp on the crank so you will make less boost than normal per supercharger pulley size. Throw your factory balancer back on.

Edit: also make sure you are very careful with the charger oil line routing and which direction you put the filter on because the rotrex chargers WILL BLOW THE **** UP if you put it in backwards as there is a check valve in the filter. Also make sure you fill it and follow the brake in exactlly per instructions or it will fail

It's a just a stillen lightweight crank pulley not under drive,but you are very observant

I installed the sc inline oil filter the way directions said,hopefully its right but I'll triple check,are you running the same kit?

milled parts for the kits, made minor tune changes, worked on revisions with the engineer, and helped out with installs.

Rad is in,most of the sc oil system is in minus cooler

Stage 2 comes with 650cc some use the 600cc and tune for them since they are cheaper and easier to get. I did contact gamma a few days ago and got there original tune for the kit ...it's updated from what Sam used and it has the throttle tables adjusted to get rid of the throttle lag and the fan tables are set to come on sooner as well......it seems to be doing better than the others and drives soooo much better...ill get my gauges in next week and then off to a dyno to test the tune ......fingers crossed hope it's close and I won't have to do a custom tune .....lol I'm sure I'll have to tho ....most can tunes are a little rich in the best case .....so I'm sure I'll have room to improve.

Ya seems like gammas moving along with ecutek slowly but getting there,custom tunes in your future lol,I don't have a dyno anywhere close to me so iam counting on good e tuning support,got abit of tuning knowledge myself from racing motorcycles and doing my own power commander tuning maps so hopefully it helps

Jinxx · 01-31-2016, 02:30 AM

I can't adjust the tunes ....only have the cable that lets me flash computer but not edit the tune ...unless there is a way to edit it on the laptop and then make the tune to flash

Jinxx · 02-07-2016, 04:27 PM

So after installing my boost gauge seems that I'm around 8lbs ....thought stage 2 was more ...ill be heading to the dyno soon to see what hp/tq I'm at ......kinda disappointed thought I would be around 9-10 but I guese I'll have to be happy with what I got .....car still pulls hard and even with drive roads was getting traction loss in upper gears so I can't complain to much ........hope I can hit around 460 whp with 8lbs

Ya you should be close to 500 HP depending on tune,I think you can still get next size down pulley for more boost,have you contacted them to see?don't remember if I asked you but have you upgraded you cooling system at all?getting the heat out of our engine bays is key to help with HP,especially where the sc intake is located,iam looking at siebon vented hood to go along with my csf rad and other cooling upgrades

Jinxx · 02-08-2016, 08:40 PM

From what I been seeing at 8 psi .. it should fall around 460 ish and with the 88lbs pulley it should be around 10 psi boost at around 480 - 500 " ish". And I haven't touched cooling other than the oil cooler .... From my understanding super chargers are not very hot under the hood and should be ok .... Turbochargers would need vented hoods bigger alum radiators and anything else you can use to cool it ......... I may be wrong tho
