I went to Swift Racing here in the DC area and did a quick three pulls on their dyno. My AFR needs a bit more tuning but its close enough for a base line before I do a full 3" Y-pipe and exhaust. I added a 2.62" pulley which gave peak boost of 13.5psi. I replaced the 2.5" crossover pipe with a 3" version. Replaced the HKS SSQ BOV with a Vortech Mondo BOV. I ported the MAF. I installed a 70mm throttle body and ported the intake manifold to match. I had to upgrade to 370cc injectors from a 96 300ZXTT. My FMU disc is now just a 3:1. I am using the J&S Ultra Safeguard to control some minor detonation above 10psi. It looks like I gained ~35hp & 35 ft/lbs in the midrange. I am happy with the gains but still need to change my exhaust. The current set up is a 2.5" Stillen Y pipe, 2.5" test pipe, 2.5" Courtsey B pipe and a tiny but quiet 2.25" variable capacity muffler from a 2000 Maxima. I should gain ~20-30hp & tq from a full 3" exhaust. Its on order so hopefully we will know soon.

Showing ~13.5psi on the boost gauge at redline.

 

What's new on the car that wasn't in the last dyno?

 

4psi more boost
70mm throttle body
3" sc crossover pipe
370cc injectors
J&S Safeguard

 

Cool.

 

It fit!

 

Sweeeeeeeeet

 

Matt isnt the A/F ratio a bit low after 5600rpm? If you brought that closer to 11.5:1 wouldnt that alone bring the hp up a bit more?

Do you have an S-AFC or just the J&S for the knocking?

Dixit

 

Very nice Matt. Now time to take it to the track!

 

Do you have a MEVI?

 

Damn. Thats all i have to say about that. Thats all i had to say when i seen under the hood for the first time. Keep up the good work.

 

Matt P Technology....

it is what it is and those is some nice numbers

 

 

Well "DAMN" is all I gotta say, seeing that beautiful blue VE sitting in the grass

 

Not to shabby Congrats dude!

 

I thought you'd gain a little more than that with extra 4psi.

 

He's not tuned up top... it's a little rich above 5000.

 

The numbers look good. Imagine what the HP would be if you had a 7k redline. BTW how is the motor holding up? Any problems?

 

little?

 

Swift has a package price for three pulls for $55.00, so I didnt have the pulls to get the AFR done exactly like I would have wanted it using my Fields AFC. After I install the 3" exhaust I will go back and get it tuned better. It just wasnt worth it to pay for more pulls since I will be redoing it in a litle while.

I thought it would be a little more with 4psi more. The need for a larger exhaust is really shown by this.

MEVI? Yes!

 

The AFR tuning realy only helps the midrange. It may be an indication that an intercooler is needed The rich mixture cools the boosted air so leaning it out seems to not really work.

 

I threw that dyno into cartest and it shows that with a 2.1x 60' you should run 13.0-13.1s @ 108-110mph on the motor. Also with a 6800rpm rev limiter your ET would be 1-2 tenths quicker and you'd add 1-1.5mph trapspeed too. You shouldn't fear the LS1s either, well at least the ones without heads/cams, from a roll that is hehe.

 

Thanks!

What does it look like if you use a 1.9 60', I have pulled that on slicks.

The only issue with the 6800 rpm limit is that I need a JWT ECU and they pull too much timing which will cause s loss of torque, plus I am already overdriving the blower at 6400rpms with a 2.62" pulley.

For poops and laughs could you add 20hp/20tq as if I had a full 3" exhaust and see what it turns out as?

M

 

he has (almost)everything. he was the first with the vi i believe.

 

yeah the first one from roastbeast

after that roadbeef took the money and ran.

 

holey mother of maxima... wtf.. nice numbers. add a biiger shot of nos and see that puppy go up higher, just hope that nothing gets hurt

 

Are you still planing on adding the intercooler?

 

Great numbers Matt, keep up the good work. Perhaps it's time to retire that S-Trim for something that would do the job more effectively.

 

Maybe a T trim, but 12's on street tires would me my goal.

Its an adiction though so you never no.

CAI any Y pipe, just couldnt get me their...

Tried the 60 shot of nitrous, after a while I needed more...

Tried the 100 shot of nitrous, but I needed it all the time...

9.5psi was good for a while, but I had to "speed ball" it with nitrous to make it feel good again...

13.5 psi is great, but I dont think I can stay with it forever...

It may be time for rehab, a Lincoln Town Car sounds realy nice

 

DOH!! Not the Town Car.


I agree that the T-trim (maybe even a YS-trim) would be a wise option. Make more power with the same boost as a result of a higher adiabatic efficiency.

 

Are you against going with an intercooler for some reason? Just curious because of the ;rolleyes: you put after it.

SuDZ

 

I doubt he's against it. It's just one more thing he would have to spend money on and add to the car. Probably close to the point where the hobby becomes a chore.

 

Gotcha. That is what I was thinking too.

SuDZ

 

BINGO

An AWIC would be great! But I think I will be where I want to be with a 3" exhaust. I still have the juice to fall back on also, a 20-40 shot will be plenty.

I want to have the car tuned by the time the tracks open again. I dont want to be moding and tuning during racing season, I dont have that much free time available. My drag slicks also look very sad just sitting around.

Give three choice...

1) AWIC $1100
2) T Trim Blower $1200 w/exchange
3) 3.5L motor $1500

What do you guys think?

I really want the 3.5L, the 3.5L would have mad torque with boost. Plus it would give me time to do some basic port work on the heads. This would be in 8-12 months.

 

How about AWD conversion so you can run 11's

 

I agree. The VQ35 would be about the most bang for the buck. But the thing would make so much torque that it would be almost uncontrollable. With the lighter A32 chassis and the amount of power you would be making I would say that 3rd gear traction problems wouldn't be a suprize (on street tires). Plus doing a VQ35 motor swap would be more of an accomplishment than doing a T-trim swap.









But I know if you have the car long enough you'll eventually have them both.

 

Gonna sponsor me with a nice set of rims?

 

(give him some rims )

 

man oh man!!! good numbers Mardi, you're lucky I didn't show up in my SC'd 3rd gen, remember from the UM meet, I'm running that top secret 1.25" pulley!!! can't wait to see some track numbers next seaon!

 

when you free flow your exhaust that should do it for sure. But Congrats those are some nice numbers.

 

u stupid!!
