so I bought this 1991 240sx SE coupe a week and 2 days ago
tuned it all up over that time and wanted to get a starting point dyno.
I bought the car with an injen intake and borla ss. catback
and have replaced the fuel fiter, sparkplugs, wires, cap, rotor, clutch, and I think thats all..

soon I will be doing a header/high flow cat. but not sure what else yet

my best run was 134.39HP and 142.59tq

now I am wondering if that is good.
I think it is decent..


any opinions?

 

HP seems a little low to me with those mods...but I could be wrong.

 

well I figure the car has 155hp stock which is at the flywheel
you loose 15% usually by the time it is at the wheels which would be 131 hp
the only mod that really helps is the intake cause a catback exhaust usually makes no difference without a header.


it is an older car that has seen better days

I guess my real question is, has anyone else here dynoed a 240sx basiclly stock like I did?
and what were their numbers?

 

on a side note an altima with the same mods plus a header puts down 130hp that is why I dont think my numbers are that bad

 

with age into consideration thats good. Most people average 130's from all the dyno's i've seen, or with IHE 140's to low 150's.

Whats next for her?

Dr.

 

I am deffinetly doing a header like I said above
maybe other small things till after I buy a house


and once I do that.......KA24DET

 

Taking considiration that the car is 10+ years old, the numbers seem about right
