Bench Dyno'ing?? Help me predict my numbers

[Erjay1]

So Im sitting at work bored out of my mind. Im getting ready to send out my ecu to get tuned at Enthalpy. Wont be able to get on a dyno for atleast the next 2 months. What can I expect with this stock T28?

Car is a 95 Nissan 240sx.
Engine is SR20DET S14 Kouki Blacktop (NA ecu)
Turbo is stock T28.
Here are my mods: Denso 550's, Walboro FP, Nismo FPR, Z32 MAFS, Apexi Cone Filter, ARP Head Studs, Cosworth 1.1mm HG, BC Valve Springs, Greddy RAS, HKS Step 2 264's, Greddy Profec B, HKS Type S FMIC, HKS SSQ bov, Megan 02 housing, Blitz 3" DP, HT 3" TP, HKS Super Drager 95mm. Can I expect numbers close to 300whp once I get my Enthalpy ecu???

Where should I set my LO and HI boost settings??

I am also concerned with the size of my HKS exhaust. I have the 95mm version. Looks like 3" mid pipe into 3.5" or 3.7" axle-back. Is that too big? Do I need more back pressure?

If the wife lets me use the credit card, I'll order a GT2871r, possibly even a GT35r kit. This stock T28 will have to do for now.

Sorry if this post sounds noobish. Just need to get an idea. Ive read about numbers ranging from 250whp - 280whp. On youtube there is an sr20det on a stock T28 pushing a bit over 300whp with an AEM EMS though.
Thanks in advance guys.

anyone?? :(

I dont know about the power but i know that turbos never need back pressure, to much back pressure could damage them i think.

Don't use a credit card on cars.

If you want to see higher numbers don't go to a dyno dynamics or you will cry.

I'll pretty much +1 whats been said above.

Credit cards on cars is dumb.

Dyno Dynamics have REALISTIC read-outs. Handy if you want to know what power your really pushing but if you want to impress your mates pick another dyno. It'll over-read and be wrong but it'll sound good in the bar.

Finally I wouldn't get caught up in chasing numbers if I were you, if the car feels good to drive thats all that matters. Chasing numbers is a mugs game and usually ends up in an expensive rebuild.

doubt youll see 300whp.. you need a better turbo... im selling my gt2871r.. its good for over 400wp.. lmk if you want it

[idahotuner]

the t28 will get you close to 300 at the wheels with those upgrades t othe fue lsystem. basically the fue lsystem is the only thing holing the sr back and you have upgraded all of that.

and i agree wit hthese guys dont usea credit card to pay for your build. save those for emergencies

[Erjay1]

Cool. Thanks for the input guys. Credit card issue has been taken care of. The wife said "No!" So thats that. Normally I'll use the CC to front maybe $1k then pay it off within 3 months for no interest.

Yeah I know better than to dyno on just about any load-based dyno. DynoJet is more of what Im looking for to ensure bragging rights with my buddies.

My other question is, where should I set my LO and HI setting on my Profec B?? Ive heard the stock T28 is out of its efficiency range around 15-16 psi. There is a video of an s14 on a stock T28 ut BPU and AEM EMS running high 12's. Guy claims 308whp and 343 tq http://www.youtube.com/comment_servlet?all_comments&v=J7ozuL5ZHvo&fromurl=/watch%3Fv%3DJ7ozuL5ZHvo (http://www.youtube.com/comment_servlet?all_comments&v=J7ozuL5ZHvo&fromurl=/watch%3Fv%3DJ7ozuL5ZHvo)

Not saying I will push this type of power. Just looking for some comments, suggestions. Thanks again guys.

You missed my point dude. I was saying don't bother using any other dyno but a DD one if you want real figures. Otherwise you may aswell stick your head out your drivers window as you accelerate and guess how powerful it feels - 350hp kerrrrrching.

Oh ok I see. As long as the car drives well and feels responsive thats ok with me. The only concern with numbers is for bragging purposes. Its a competition between my buddy and I. We've been competing for years with anything we do. I hear what you're saying though DD or load-based will give me REAL numbers. Well I think Ive gotten my answer.

Oh yeah, only question I still have is my boost settings on my Profec B.
LO and HI....what should I set them to after I get my ecu back from Enthalpy??
