Here is the deal. I dyno tuned my friend's car on stock sequential twin turbo. The car has the following mods:



stock unmodified twin turbo running sequential

ported motor with the racing beat street port template

R33 fuel pump

550 cc/min primary and 1300cc/min secondary

HKS twin power

cold air intake

large stock mount IC

downpipe, midpipe, restrictive single tip HKS exhaust





The dynosheet shows the a/f. At some of the runs, the a/f at high rpm looks lean like crazy but it's not. The o2 sensor at the tail pipe blows off during the run. The car is still running rich. The boost level is 1.15 kg/cm2 and the intake temp is at 45C measured by power fc.



I believe if I lean it out a little and have him change to a higher flow cat-back exhaust such as the APEX GT, it shouldn't be a problem to break 400rwhp on stock twins. The turbos are just stock, not modified or anything and they have 30k on them already.



Now this friend of mine wants to get a 3 bar map sensor and want me to tune the car to run 1.35 kg/cm2 on stock twins. I am sure you guys want to see that dynosheet too. =)

looks good. somebody else made that much power my friend anthonyNYC..... :bigthumg:

 

Sounds like B.S. to me Chuck sorry, But I know for a fact that the racing beat templates are small. Smaller than my ports as a matter of fact.

There is no way that you are making that power on that car.. I want to see the video.

 

if you think thats BS, i'm not even gonna tell you what john D (boostin7) just dynoed with stock motor AND stock turbos. at 17psi he made more power than some guys with ported motors and single turbos

 

roan you beat me to it ! i was gonna say john d is probably putting down 400rwhp.....



he is the MAN! :bigok:

 

what psi was this dyno @?

 

Its true.....ye it is



402rwh and 356 rwt @ 17.5 psi...



injectors maxed out .....4x850cc

map sensor maxed....1.13-1.14kg/cm2....17.5psi



here's the sheet...

 

correction vosko, john d is putting down 402rwhp!!!!!!! on stock motor and turbos!!!!

dont hate FD3boost NY/NJ guys are known for doing the impossible.

i'd love to see riki bring his ported single turbo car to atco and loose to a stock motored, stock turboed car

 

man thats nutz! Those are awesome numbers, so it really is all in the tuning.

 

and another....
