Well i am going to the dyno next week finally and i was wondering what you guys think my numbers will be with this setup:

V2 SC w/3.125 pulley
Hotshot Headers
ATP 3 inch exhaust cuttout
Warpspeed Test Pipe
Warpspeed 2.5 B pipe
Stock Muffler
And i will be using a SAFC to tune with.

 

298whp...? Just a guess

 

**** . I was hoping for around 350 whp

 

Do runs with the cutout open and closed, for comparison.

 

i deffinetley will. should be a very easy before and after comparison

 

Just under guessing. I don't see 350 but I sure hope you get it.
Not sure how much the cut out gives you???

 

What?!?!?! When did this happen?

I want to go. We need to get a whole group going.

Why didn't you come to BWW last night? There was like 9 4th gens but the 5th gens were flaking out.

 

I went out and got hammered last night. It was a good time. I also thought you and frosty didn't plan on going. Plus i didn't feel like washing the car

 

Yeah i am just hoping to see the same results from the cuttout as I would see with 3inch exhaust. Stephenmax hit like 340 something with a similar setup( except he is running a smaller pulley). Owell just wishful thinking

 

are you on stock ecu, injectors? What base fuel pressure are you running if you have an adjustable FPR? And what FMU disc are you running? I am asking because I am running the same pulley, and also use an SAFC-II to tune, and I am having troubles tuning my car, so I am interested as to what you will pull.....I am guessing 326whp. I am sorry if these are dumb questions but I am not familiar with your set up other than what you posted.

If you have the cutout, does the test pipe and b pipe matter?

 

No it's not a dumb question. I have stock ecu, running stock injectors right now(I have to install the RC 440cc) , and i have to install my SARD FPR. Right now i am running the 8:1 disk.


Also i hope you get your tunning issues worked out. Are you running a adj FPR. I assume you are but just wanted to make sure.

 

Well it is a boost activated cuttout and is set to open at 5psi. So i guess it will only matter on one are of the curve on the dyno sheet.

 

Yeah frosty didn't go. His car being in the shop and all. I went and it was pretty cool. Bobby came in the parking lot kind of fast and some people tried to yell at us. Some of those people are getting pretty hostile.

I tried to call you but as usual you didn't answer. Oh well. Let me know when you are going to dyno. I may just go to watch if I can't get one or two passes myself. I think I am going to the track next wednesday. Frosty and I leave for colorado early next saturday morning so I may or may not be at BWW next thursday. I will try to go though.

 

cough<358>cough

 

yes, I am running the AEM FPR its set at ~25psi at warm idle

--so you are running stock fuel pressure right now?

 

I'll bet you'll be between 260whp-290whp.

[maxi-dose] running a 2.87 did 260ish@10psi with automatic and Y2KevSE did 302ish@11psi with automatic. [maxi-dose] wasn't tuned, but Kev was.

 

Good luck Chris!

 

Alex i bet you $20 its over 310 whp

 

You've got a bet!!!!!!!!

 

BTW, make sure this is a DynoJet 248c or similar and GET THE RUNS ON A DISK.

 

Alright i will do that. You really think i will still be under 300whp? I would think that the headers and exhaust cuttout will yeild some significant gains.

 

Just being Negative Nancy, since breaking 300whp seems to be a WALL, even if you have all your pieces lined up.

This guy has poor tuning, 2.87" 13psi pulley, fmu, catback, and a ypipe and didn't break 300whp: http://forums.maxima.org/showthread.php?t=369324

So, knock off his 2psi ~20whp VS your headers/his ypipe and your cutout/ his catback should be close.

Good luck and depending on which way the correction factor goes, if you're over 300whp, you deserve the $20.

 

Also, one of these days you should toss that cross over pipe and make yourself a CAI for another 10whp/1psi at least.

 

I know, i always think negative since i always get screwed on things. Didn't Stephenmax gain a good bit of power from the headers?

 

281whp. I don't mean to be negative but there are turbocharged 5 speeds that aren't putting out much more than 350hp, and you're a supercharged auto...

 

Chris'smax,
I wish you the best in luck in trying to reach your goal. But i have a feeling that you will be just under your goal.

 

Once again the 19" rims are not going to boost your numbers on the dyno.

 

thanks guys for the encouragement. I guess the dyno will tell all. Hopefully it will be semi decent

 

Yeah you should be putting down something up there.

It will be higher than mine, for now .

Have you checked your VIAS? If not it would be a good idea before you go and find out it's dead.

 

*DYNO**DYNO**DYNO*

Just playing Chris...any ETA?

 

are we talking SAE corrected #'s, actual un-corrected#'s, or Standard #'s.
SAE is what we use in Virginia, and it just so happens to give you the lowest #'s
good luck, i hope you join us in the 300hp crew

 

I wana seeeeeeeeee....

 

well guys it seems that everything has gone against me this week so i will have to reschedule. First off i got sick as a dog this week and then cuttout atp sent me seems to be malfunctioning. I opened the valve wtih my hand and now the valve will not close all the way. Is it possible that when i opened it the actuator built up presssure inside it keeping it from closing all the way?

 

If it did, it isn't working right. Can you apply a vacuum to it and see if it shuts all the way?

 

i hooked it up to one of my vaccum lines last saturday and it didn't close nor did it open when i revved the engine. I guess i need to send it back

 

it needs boost to open and you dont get boost by just reving the engine. the engine has to under a load to make boost

 

How do you figure that? I don't mean that to come across in a mean way but i really don't see how that is right

 

he probally means for a turbo or something but a s/c makes boost whenever u increase the revs.. is atp the company thats in jersey? cause my friend wit a wrx is plannin one and if its not working right i might have him go elsewhere

 

thats what i thought. ATP is out of california and they deal with alot of VW and Audi
