Nice Car dude, but if you lower it and put better fitment wheels it would look alot better on the outside.

Edit: Did I read this right? "54mm wheel spacers (rear)"

[Flybert]

That's about 20-30hp lower than normal for a stock cam SR using one of those turbos. Get some cams and go retune it. Fuel looks way too rich above 6k. Looks like your dipping into the 10's.

[SoSideways]

Yeah it seems low... Not enough timing? Too much timing?

Also, don't those turbos hit full boost by 3900rpm? Looks like full boost came on around 4000-4100rpm.

[wootwoot]

I'll bet money on boost leaks and bad timing being the error. Roanoke is kinda up there too isnt it? High elevation? Thats not bad, nothing to be sad about. The turbos dont make to much power without supporting mods. Cams/intake manifold at that power level get soooo much extra power because of them being restricted. More so in the cams for restriction

How does the look of his car have anything to do with the dyno?

[steve shadows]

what are the exact specs of your turbo

[NismoRacer1]

Yea i've been wanting new wheels for a long time, but unfortunately have to stick to a college budget.

As for my numbers, the fuel is fine, the lowest it hit was 11 and that was at the top which is just me being precautions. The timing is pretty weak and that will be dealt with soon enough once I can get some help from a friend. Should be able to pick up another 15 hp or so with a better tune. I was very surprised to make as much torque as my roommates KA-T setup on the same turbo, so overall I'm content with what it did.

[NismoRacer1]

Got a couple videos uploaded to myspace

One is here on my profile for those of you that have myspace:

http://www.myspace.com/nismovt

There is another one uploaded to myspace as well form a different angle, but you'll have to search for it

[SoSideways]

Myspace = fail.

Please use youtube or something where EVERYONE can/will access?

[SC_S13]

thats solid man. good luck on future endeavors!

[nissanberto]

your myspace profile is set to private.. but from the previous video it looks really good... i wish i could afford an sr20 right now haha.

[kuramaya]

Keep it up, there are more HP's in that Turbo brother. Those are S14 T28 Numbers with Cams...keep us updated!

[NismoRacer1]

We've actually found the problem for the dip in the torque curve; at 4000rpm timing is 18 degrees at 4500rpm 14 degrees and at 5000rpm it goes back to 18 degrees. Not sure why it was set like this but it is corrected now; should make a significant difference considering that is right where I would have made peak torque.

I've been really busy lately, but I will try and find another way to host the videos so more people can access it, i forgot that I changed my settings on MySpace to private; got to hide those drunken retarded pics from employers.

[NismoRacer1]

Ok here are the videos that anyone can access

enjoy

[NismoRacer1]

Bring this thread back from the dead....new dyno numbers from BRE Motorsports in NC

Fixed the dip in my timing map and made 327 this go round

Now I'm shopping for an intake manifold and Tomei 260 cams....then a more "professional" tune, should get quite a bump in power

[drifting_changed_mylife]

sweet car man! keep it up

[johngriff]

you had a nasty dip in your timing map?!!?

LIKE FF1?


You should probably tune the ignition map on the dyno, thats still low.

Correction on a dyno jet is 10-15%, so with the median being 12% and 327 wheel, you are putting down 287 wheel.

Find a dyno jet, tune the map under load. The whole pull looks pretty bad, you are looking for the right stuff with the cams and manifold (tb too).

[NismoRacer1]

Well what you see is my old dyno charts....and it made 290 something on their dyno (not a dyno jet) and the 327 was with whatever correction they told me.

This tune was my roomates first attempt and it feels great and runs great, but I just didn't want to spend the money having it really tuned until I was done with mods.

I'll try to get the new charts and videos and what not posted soon...i'm in the process of moving so the only internet access I have is at work.

[m91silvia]

SR looks like it can make alot of power on the stock block with only supporting mods and a bigger turbo!

Hence the reason why i'm swayed from KA to SR!

[johngriff]

Stock block SR is fine as long as you tune it right, and don't detonate it to death.

[m91silvia]

yeah... that seems to be what the dyno graphs are proving lately.
i've seen at least three where they upgraded turbo, cams, injectors and fuel management and they all made over lower 3xx hp on pump.

crazy!

[johngriff]

On sunday, steve shadows made 388whp with an upgraded turbo, cams, manifold, injectors, and haltech. 17psi on horrible California 91 octane. That is uncorrected, nice and low. If you whore up corrected numbers, That is 434.

[McRussellPants]

Ugh, every 2871 dyno I see makes me hate it but then the owners are always like "I fixed alot of stuff and now it doesn't suck" but don't post the new graph


anyone got a good 2871R .64 SR20 VTC dyno?

[max_POWER]

so is this the .64 or .86????

[steve shadows]

I think he meant to say load bearing dyno like dynodynamic.s

[johngriff]

yeah, exactly.

I've already checked out completely, vacation tomorrow, I'm not even here.

Post yo graph foo.
