We just finished the tune on my evo 9 and here are the virtual dyno results.

mods include
FP BLACK
ets 3.5" with piping (short route)
perrin filter with fp intake
fic 1250cc injectors
megan tbe w/ o2 housing
arp headstuds
hallman mbc
walbro 255

 

nice what fuel and boost

 

93 and 28-29...afr at redline is 10.8-10.9

 

Living proof that you dont super lean AFRs or cams to make good power on 93

 

Nice job.

 

Hopefully Cams and a 110 tune will be next , And we can update you guys with some real world power increases on this large turbo .

 

Get some cams for that turbo

 

^ You didnt by chance get a before after on your S2s did you , Ive been looking for some hard data on them Thats what the OP is leaning towards .

 

Sure did, although with the BBK turbo. Stock cams, 94 octane, ~29psi, it made 404whp STD Dynojet. After the S2's and speed density it made 450whp STD Dynojet. 46whp gain but also added speed density at the same time. Results should be even better for a Black I would imagine.

Thanks I will try and see what just the cams do when the day comes with as few other changes as possible.

 

Nice result. I wouldnt do 110 oct & fp black on stock block

 

?? He'll be fine as long as the timing/torque is kept in check. Stock block here. If you mean going to ethanol over 110 then that makes sense but the OP may/may not have easy access to E and race gas may be his only option.

 

Trying to limit torque to about 400 WTQ so basicly the 110 Will be to increase response , safety , and topend , and will likely be run on the weekends for those playdates

 

Well in that case should be good,
Good luck

PS: wish we had a graph where the pull starts from a lower rpm,
So that we can see where the peak torque is achieved

 

any reason for such a rich a/f at redline? to me it seems like its not making nearly as much hp as other fp black cars. also, who tuned the car?
