4 Attachment(s)
My first post on the forum, If my spelling is like ---- its because im from Sweden :)
Have some questions regarding timeing and AFR targets on the 99 miata. I have a homebuilt kit width following spec: 99 Stock engi. Custom mainfold. TD04-15T turbo (from saab 9000 aero) 2.5" exhaust width no cat. 425cc injectors Diypnp Currently running 7-8psi. questions are: how much boost can the 99 engi take? Are my spark and fule table ok? pics on build: http://www.garaget.org/?car=247712 (Swedish site) |
boost is the measured restriction in the intake.
Basically you are limited by TQ the engine can handle and the fuel type. on the engine side Check around for a compressor map to see how far you can push your turbo. To me your AFR target table, 2nd picture takes fuel out too soon. Fuel table is the one called VE table using speed density, Alpha N, etc |
