Gilhuly Posted December 14, 2005 Report Share Posted December 14, 2005 I know this place has dyno machine in CT, i know they do lots of EVO/STI.http://www.pruvenperformance.com/Yeah, I've seen them before. They look fine, but I wish they did some euro/bosch vehicles. I suppose it doesn't matter much, though. I simply want to play w/ some cam timing strategies and have a dyno I can send to Upsolute if necessary for an update to my chip Link to comment Share on other sites More sharing options...
Vos Posted December 14, 2005 Report Share Posted December 14, 2005 Perhaps a silly question, but is there any special consideration required to use these on an a car with variable valve timing? I believe the 99+ S70's (like my 99 T5) have variable valve timing (I may be mistaken?), and did not know if this would impact it at all.... I presume there would not be, as you say they are adjustable from the factory and you have to set 'em up at 0° anyways to use them in the stock setting.But thought I would ask just in case!Thanks B) Link to comment Share on other sites More sharing options...

The other stays static. That is the cam that you can adjust yourself with the cam timing wheel.Also, they are not necessarily 0 degrees at the stock setting. It varies. 0 just means TDC.

ziddey Posted December 25, 2005 Report Share Posted December 25, 2005 mine seemed to come stock around -1 intake and +3.5 exhaust. i kept the exhaust and upped intake to about +3. i'm sure that although the tool tick marks have a very tiny margin of error, there's a lot of user error in this. i tightened all the bolts finger tight and then went to adjust and i did do fine. however, depending on the angle of viewing (i'm not sure if i'm looking at it directly straight on or slightly to the side, and it makes a big difference!!), and also there seems to be a little bit of give in the pulley, especially when i go to tighten it again. i'm hoping that that doesn't throw it off any.i did this as well as put in new spark plugs (gapped at 0.025) at the same time. at first, i experienced cutoff quite a bit (running mbc at 10.5psi right now in winter), and then i got a lot of extreme timing pull and i guess after it pulled all the way, i got cutoff again. this happened for twenty miles and then went away. (roughly). i hope it doesn't come back. will definitely raise boost and tighten wastegate again tomorrow and see how it is.but definitely so far, the shifts are so so so much smoother. and because the power got shifted forward, the car doesnt seem nearly as fast according to my butt dyno. however, i had a friend in the car and he said he never saw my tach race to the end that fast before. so i'm sure it's doing well!thanks slater Link to comment Share on other sites More sharing options...
Boost Addicted Posted December 25, 2005 Report Share Posted December 25, 2005 From what I understand the intake cam controls ignition base timming, so after I started it I reset my ECU and the idle instantly improved. Link to comment Share on other sites More sharing options...

JCviggen Posted December 25, 2005 Report Share Posted December 25, 2005 because the power got shifted forward, the car doesnt seem nearly as fast according to my butt dyno. however, i had a friend in the car and he said he never saw my tach race to the end that fast before. so i'm sure it's doing well!Advancing the intake does not shift power higher into the revband...if anything it lowers it a little. I run +1 ex -1 intake now and I notice I've got a slightly better top end (stock was +5 +0) but I didnt make up 30 horsepower anywhere for sure...i think your cams have to be set pretty badly to make up that much. But its a nice tool to control your powerband better. All in all the car feels pretty similar, but its a lot more agressive high in the revs 2nd/3rd gear. 4th and 5th I'm not sure yet...some slight issues there.

ziddey Posted December 25, 2005 Report Share Posted December 25, 2005 sorry i was a bit confusing. by forward, i meant earlier in the revband Link to comment Share on other sites More sharing options...
