Turbo Technics S280 Turbo Kit Dyno, Virtual Dyno, and Datalog Thread

Yeah most likely he will just further adjust ur fuel and ur charge temp compensation tables. I was getting alot of knock up top even in colder temps and my charge temps were shooting up 20+ degrees. May switch up my intercooler at some point (whoosh v2).

I'm gonna get a bap if I upgrade but we will see how ethanol helps.

fwiw I have a BA intercooler and do not heatsoak

 

[JDG]

Revision v7 w/ aux fuel (93 octane)

The spool is insane. AFR look much better but still seeing knock. Need to investigate this BA intercooler.

looks great! you think the knock is from heat?

I think it’s a combination of the added heat and not enough octane. The knock will go away on ethanol I’m nearly sure.

@MagnetiseST sent me a log and with the BA intercooler he sees an 11 degree rise in charge temps. I see about a 15 degree rise during a similar pull. He is in Florida though so definitely an improvement over my FMIC.

looking like I"m going to need to run a blend!

Will need aux to do it.

I think its mostly just the octane at this point. We're both at the limit of 93. It stinks these cars really don't like pump gas but it's a low displacement motor that's not super high in compression so you have to run a ton of boost.

yes going 4 port

Single port aux or four port?

Single

 

[MagnetiseST]

Single

I'm heavily questioning going this route then, if SPA can net over 300whp on 93 oct then I'd be happy as a clam.

does the stratified aux fuel ever go on sale?

I bought mine used for 400$.

 

[MagnetiseST]

With this turbo you won't max out the TBI aux injector system.

so theres really no point to ever going 4 port?

Guys, go back to the other s280 thread with discussion over auxiliary fuel. I created this thread so that we could leave the repetitive nonsense discussion out of it.

I keep getting the threads confused...

Back on topic. Nearly complete for 93 on 4-port aux fueling. Took a bit of boost out to control knock. This revision has virtually no knock.

Curious on whether my tuner will pull boost or pull timing. I am hoping to run 30psi.
