Changing extractor definately helps, it frees the engine up and gives better torque at low revs for a 4-2-1 config, just don't oversize the rest of the piping.

QUOTE(m|ng @ Aug 4 2006, 09:14 AM) But my Extractor is already 4-2-1...Er..Stock lar of coz.. Stock one still not as free flowing as aftermarket ones which have their length tuned also. The heatshield IIANm cannot be fitted back.I saw Hotbits extractor.. Not very exp..i think like rm300+.. But Dont know how good is the performance increase.. Heard of Powerzone extractors..but dont know where in Penang can I get it. And another concern for me is, Will the original heatshield be fixed back after I change extractor? Some have took it off coz it wudnt fit anymore as the extractor piping is a bit diffrent in length and curve.  |

QUOTE(m|ng @ Aug 4 2006, 07:29 PM) Oh, If thats the case..what's the remedy? Buy those heat insulation wraps? Don't heat wrap your extractors, it kills them faster because it pushes the temp up close to material limits.Coz If left as it is, The engine bay can get quite hot rite? as the extractor is normallly very hot. |

QUOTE(m|ng @ Aug 8 2006, 09:01 AM) Adding stuff like airfilter can reduce ur RPM at high speed? Air filter doesn't affect engine RPM.I tought its the gearbox's settings? My dad's Corolla SEG pumps 3.5k rpm at 120km/h/ Then ur car shud be very fuel efficient? |
