The simple fact is that timing for maximum power is where it needs to be. More or less will make less power. N/A motors that are set up well with polished combustion chambers and pistons with a decent amount of quench with high compression and a good intake velocity to fill the cylinders will need far far less timing than a stock motor. All that quench and compression gets the flame going across the combustion chamber really fast. It doesn't take much timing before you are too advanced. Word and it comes really into play when a cylinder head is flowin like crazy yo. Seriously though a head that is flowing over 300 cfm doesnt like timing. I just did a map stock h22 block ported manifold/69mm tb china ebay header that is killing atleast 10-15 whp imo dhracing ported head off the shelf cams I did a basemap for the car close has I thought from what I have done with the h series all motor tuning. Dave from dhr did the install on the head and cams I wasnt there when they dynoed cleaning up afr Im confident I could of gotten another 3-4 whp. Car liked a very mild timing map. Imo that car with a proper header,no exhaust and a real inatek is in the 235 whp range. Not to mention that dyno reads way low. The car is raping everything in hawaii. http://videos.streetfire.net/video/4...ea0005d1cf.htm mad vteccccc |

An all motor car with a single throttle body shouldnt take more than 2 hours total |

I was talking about JYR car.

Re: JYR's next adventure. Tuning. My on-going thread...
Dyno, ill take it back when its all done. the dyno time is pretty homo. $50 for 2 pulls. More for tuning, and they dont do it by the hour unless you have them tune it. I'll tune it on the street, like everyone else.
JDM dude: "you want a Power FC", I will tune for 25000y ($250) me: "---- your power FC" :P I dont plan on rushing into this at all. Slow and easy, and I will learn a little at a time. I'm still waiting on igy to get back with me to chip the ECU and put the datalog cable in. Theres a map on Chris' site, LSvtec, intake mani, ITR pistons, i think im gonna give that a shot for a basemap...and go from there. Henry: JDM doshound. (sp) Shes about 3.5 months old or so. Little thing thinks it needs to ---- with everything in site. :S |
