It has been hot as hell last week and this week. So, for Rikki to get such great number in 94+ heat is somewhat hard to believe.

You know, if it were not Rikki, everyone would have congragulated Rikki. However, because of his sycophantic over eager lap dog brown nosing for free tuning, he has lost credibility with some on this forum (well at least moa). Therefore anything he spouts about PFS will be looked at very critically.


Not saying that Rikki did this but I've seen one quick way of getting better number is to put very light smaller diameter wheel on so that it would accelerate the rolling drum quicker. Because it's the acceleration of a given mass that gives HP reading, the quicker you can accelerate it, the better the HP reading.

 

Rikki you made the stmt that you got increased TQ with no additional HP. That is impossible, HP is just a calculation based off of tq and rpm. If your tq goes up your hp has to go up, hp is merely a math calculation from tq. The dyno measures the tq then multiplies that figure times the rpm and divides it by 5252, the end result is your hp.

If your tq is climbing with additional boost and your hp remaines no different there are problems with the hp calculation.

Maybe you just didnt explain it right or something.

STEPHEN

 

He explained it right.... I was right there. When they added more boost the hp went no where. It was out of the turbos range but did however increase torque as well as create boatloads of heat in the engine bay.

 

Guys, you are missing an important piece of information. I don't think RIki's car coudl even run 11 pis. with an open exhaust, inatke, porte engine, even if he had a ported wastegate, I doubt he could keep the boost below 14 lbs on the top end. I know with my car if I set the boost to 12 it still runs 14 once the secondary comes on. So even if it may have been set for 11, you must have some crazy WG to allow you to keep i there.

I rememebr the first dyno run I had at KD rotary, dave was freakign out, until we analyzed the info from datalogit, and even though I made like 340 at 12lbs, it really wasn't 12 lbs but about 13.5. after 5500 rpm.

I haev always know Riki to be a honest guy so I doubt it is bullshit, just porbably more to it than meets the eye.

 

Keep in mind that Ray ran an 10.1 and 138MPH so if the PFS dynojet is bullshit, I want some too.

Some of you guys - and you know who you are - just can't stand the idea that PFS knows how to tune these cars.

Rikki, way to go.

 

What ever happened to the good old days when bench racing was based on pure 100% USDA bullshit? Now everybody is using a diagnostic tool - the dyno - to show how fast their car is, and getting all worked up about who puts down what. At least its fun to watch on the internet that way. When I used to work at a domestic tuning shop up in Rhode Island (during high school) we had to drive all the way up to New Hampshire to back up the talk... but I digress.

Nice meeting all you fellas at the shop last night. I saw Rikki's car and I think I figured out what his secret is, actually Ray told me. Instead of NO2 they are pre-mixing pulverized puppy dog tails. There were literally hundreds of tail-less puppies running around the fenced in area behind the shop. Sad, but necessary I guess.

Later - oh, here is a recent pic from the DC Grand Prix autoshow:

 

i really do not think that the numbers are *too* far off, but very strong nonetheless. some c16 could have been in the tank, that would help as well.

i am an advocate of the "more than meets the eye thing"

the inacurate boost theory could be right, of ryan might have a trick up his sleeve. who knows, who cares?

one thingh should happen, which should precipitate two reactions.

1. seperate dyno, appropriately accomodated by tim b. or artguy, as implied.....do the ****** job and see.

reaction...

1. numbers do not match, and everyone will say i told you so.

2. numbers DO match with an accepted marginal difference, and the naysayers are silenced...

i am a believer in the innocent, i think that ryan could be on to something here, and am anxious for the unbiased dyno run.

i was *told*, by cam at pettit, that MY car [same as ryan's setup] *should* put 340-350 @ the rear wheels with some race gas. however, i fail to believe that until i really see it for myself....

Um, i think you missed the point entirely. If tq moves hp moves, its not a PFS or KD think, its not a rx7 thing, hp is a math figure its not a measurement. If your tq goes up your hp has to go up as well. If it doesnt the dyno isnt calculating hp right.

If at say 5000rpms your tq goes up 15ft lbs then your hp goes up 14.28 at 5000rpms. Its a formula and there is no changing or bending it. Thats how it is, if its not doing that then they dyno isnt calculating it right.

Dont get me wrong I'm not saying he didnt make 350rwhp, I'm just talking about this statement that was made and saying if its true then the dyno was wrong.



STEPHEN

 

double post sorry.

STEPHEN

 

ryan and all....

to add to my above post, that was 10-11psi as well....i forgot the boost quoted.....that was the whole point of teh post....

 

I take it by that statement that rikki had some race gas that might make up for the discrepancy in hp??

 

^seems like it^

that's what i thought, and no one else took that into consideration...

 

I can understand how with very aggressive porting he can get to those numbers. Thats probably the difference, most shops dont do real aggressive port because it requires timing changes. Peter did a large port for Rikki cause they knew they would be tuning it and could change the timing for it.

Anyshop can do major port but most shop's "street port" is just cleaning it up a little because that doesnt require tuning changes, it can be run with the stock ecu or upgraded ecu's timing and fuel maps. Doesnt mean they cant do large ports but they just dont bacause there is tuning required. You have to have some way of tuning the timing for it.

STEPHEN

 

Sweet numbers Rikki, I cant wait to see your ride on the 1/4 mile . Its funny that so many people dont believe this can be done .Numbers dont lie , nice dyno run dude.
Do you think Gordon has some more dyno charts to litter this thread with ? Let it go Gordo, you won your case, be a man and stop the "my thread is longer than anyone elses " game ?


Again nice run Ryan !

 

Your torque VS horsepower complaint is based on having that extra torque at the horsepower peak. There is no reason not to believe the extra torque was present at the torque peak and fell off at the horsepower peak. This is why, in reality, peak horsepower is not so useful. It only happens at one point on your graph. You can't stay at that RPM forever. Average torque throughout the rev range is what gets you down the track faster. Look up a few posts. 10.1 @138 mph is great, but I've seen an RX-7 that does this EXACT quarter mile with 505 hp at the wheels not 620. That 505 hp car had nearly flat torque from 4500 RPM to 7500 RPM. This is more what I want

 

Oh yeah Ryan, I think I can get those slicks mounted for free and in the worse case it would only cost 9$ a tire.

 

Yeah numbers don't lie! Look how we got our president, or how Bonds and Big Mac broke the homerun record (using the juice, no not nawss).
The important thing to remember is the differences taken to get those numbers, and I have to agree with Gordon. They don't add up, Rikki is hidding something and he knows it.

 

Rikki, so are those numbers on race gas or pump gas?

 

The purple motor eater???

 

Thanks Rikki, that makes it easier to understand.

 

Ok, first I am bored as **** at work today, so I have a excuse for my speedy response on this thread.
Damm you must be one bitter little man Gordon .But thanks for not being so diarrhetic with your response this time .
