i just got the car from the customer today and my dyno is booked so no base number. but as iv'e read there all around 200-212 whp so i will just go off that.

when done i will post full dyno sheets with A/F and timing also i will tune the V-PRO to try to achieve higher whp numbers

 

actually, 220-240 is base, usually, on a dynojet.
what part of "usa" are you in?

 

i have had a couple of 6 speeds that pull that but not automatics. we are in Maine (eastcoast)

 

What will happen if I allready have Highflow KAt and aftermarket exhaust and install the HKS Kit?

 

with a/m cats, you will be lean. exhaust isn't a problem.

 

What A/F ratio do you aspect with highflow kats? Did someone try it out?

 

Dont want to reinstall I love the sound

 

don't know. i'm just telling you what hks told me. i'm going to install it with a/m headers and have technosquare try to tune it via the ecu. i'll let everyone know what happens, but hks says their out of the box kit requires stock headers and cats, or you will be lean. how lean, they do not say.

 

Oh boy more lean is more power I think. Have to install AEM UEGO and check it out afterwards. I think the Greddy TT is easyer to tune but harder to install.

What a ****ing desicion.

 

well...actually, more lean can mean blown engine. the hks kit is the most conservative fi kit offered. the greddy is the most aggressive and has blown up the most engines. there are many other good, safe choices in btwn, vortech, aps single and twin, turbonetics single to name a few.
i chose the hks cuz i wanted to start conservative. sounds like you need to take your time and do a lot more research cuz you named the two extreme setups, which are vastly different. check the forced induction forum.

 

this graph may help you:

 

well the car started up perfecly. i will be dynoing it in a couple of hours. i drove it around the parking lot and it drives good. i will let you all know the A/F, power and torque as soon as i am done!

Mods so far:2004 Nissan 350z Roadster Automatic
HKS Rotrex s/c kit w/ ported compressor housing
stock headers
stock cats
stock exhaust

 

hrmm.. really considering the HKS kit now.

good thread!

 

Hope you didnt forget to prime the unit before start up?

 

Is that what happened to yours Pumped?

Did aam flash your ECU for the HKS or did you go with the FCON?

 

i actually have a pretty good way of primming these s/c that works great.

 

dynoed the car friday and it made 272.39 whp and 282.63 torque
93.12 degrees f 41% humidity

a/f stays rait between 11.7 and 12.0:1

 

from what I understand is that if your rotrex unit came with the yellow caps in the oil holes you do not need to prime the unit. The system does not have the prime pump like the older models where there is like a boat fuel pump on the oil line.

 

Wow.. Interesting. I'm not really a number guy, but what kind of dyno was this on?

Overall, what are your feelings on this SC?

Thank you!

 

are those sae numbers?
