I don't know about OC but there is a shop I use in Chatsworth called Specialty Z. They specialize in Z's and GTRs but I got my baseline done there, and my exhaust dyno there also. All done in 6th gear. $100 for 3 pulls with printout.

348WHP all stock, 377WHP after Borla....you bet I'm going back after the tune.

I'd be a very happy camper if I break 400whp with stock headers and main cats in place.

We should do a tuned ISF dyno day. lol.

And maybe you missed what I was trying to say, maybe I articulated it wrong but I said:

So, I guess I mean that the standard that has been set on this forum for all these years to measure WHP is the standard that should be used for all modifications done to the ISF. That is the speak we have been using for a very long time now and one we all understand. Varying from that is confusing (at least to me) and does not measure results against the baseline we have come to rely on.

Case in Point - The post just above this.

Dyno number comparisons accross different dynos are meaningless. There is no standard way to do it and each dyno can be calibrated completely different.

The only thing that matters is how the car performs on that specific dyno before and after the upgrade. As long you use the same procedure (4th gear or 6th gear) on both runs the numbers are relatable (but only on that specific dyno).

Now if all dynos were calibrated exactly the same, all throughout the world - we should all use the same procedure and we can compare numbers.

I think when the tune is released, we will see higher than 400whp as different dyno results come in.. So far, RR has only advertised what power was put down on that specific dyno.

Thank you Messers. Joe Z & Flowrider for your inputs (btw Lou, I have EXACTLY the same mods as you, except for Joe's intake). I too await Mr. LBR's weigh in, he's generally more prompt with his opinions.

Exactly.

People are too concentrated on the final peak numbers of one certain dyno when they should really just pay attention to the gains. It's all relative to what dyno you baselined on first and it seems just too hard for people to comprehend that.

I've been dynoing cars since 1998 when I was daily driving a 450whp GSR, I've been to countless different dyno days and can attest to how different one reads compared to another. Heck even on the same dyno from daily changes in time, weather, humidity ect. At least with the Fabspeed dyno it's climate controlled so at least that's one variable that has less of an impact on the results.

i like how everyone ignores the question when ppl ask about the tune on a stock car lol must be minimal gains to not bring it up

Lou,

I was just responding to the part of your post where you claim Rafi said 400whp cannot be reached with I/H/E.

Also does it really matter if they didn't follow the "standard" in dynoing the car in 6th 1:1 gear? Also Rafi already explained they dyno'd 4th in rapid successions without long cool down periods, sometimes with the hood closed jacking up IAT's to better simulate real conditions and expose any flaws in the tune. I also noticed that in 6th, the car hits the speed limiter before the rev limiter so you will get an incomplete dyno run shy of a few hundred RPMs.

Gains are gains, hypothetically what if he dyno'd in 6th and baselined higher, then again after the tune. Gains will still be 40whp and the higher number would be for just bragging rights.

I don't think Rafi has tuned a stock car yet, I would expect about the same outcome 25-35 hp/tq

Well from the other thread, Vivid claims to pull 30whp from a stock car with no other mods and this was Rafi's response,

"Firsts off, we have been tuning now for for thousands of miles and months... amazing that they did this so fast, after asking for a demo car just a week ago

Second... NO WAY just a tune is going to make 30whp... NO WAY."


There you have it, looks like tune on only a stock car will probably yield a lot less. Unless things have changed somehow.

If dyno numbers are what you guys are after then my car is the baseline to go by. I have 15-20 dyno sheets from the same dyno jet dyno. I started with a stock baseline and tested every mod and tuning change with the same wheels/ tires on the car.
I'm sure tons of dyno numbers will be posted by the time my car comes out in the spring but I'll be sure to get it on the dyno as soon as I get enough mileage on it.

RCB, what was your baseline stock on the Fabspeed dyno? Also what gear did you do the pulls in?

European auto source has a dyno jet and they in Anaheim. I called them up last week. I was thinking about doing a baseline pull Monday or Tuesday. Maybe we can do it together and compare numbers haha
