srmotorsports post hp dyno results!!
 

srmotorsport posted dyno results but i cant get the page up anyone else??:mad:

No.. I cant either...

It's up now.. www.srmotorsports.com

It looks a LOT like that dyno graph has been edited.
Where is the dip when the intake tract changes over?

In general the curve looks way too smooth.

hmmm i wonder if rx tuner will be making there on testing on pruducts that come? i know sports compact always does it they pick a car every month i believe and test the cliams companys are making .......canzoomer i wrote to you about buying stage 2 you never answer my email

If you magnify the image several hundred times, you will see that the line was superimposed on the graph. Just my two cents....I think its fake.....

wow, thats pathetic

Yeah, I noticed that too.

Up Close look
 

Here's an up close look. As you can see, their is a difference in color. It may also be that the program they are using is cheap.

I of course do not know the overall validity of the dyno and will not speak for the numbers, but a Dynojet has a feature called smoothing which looks to be enabled (look in the right hand top corner) and from what I can tell at level 5 which is the highest level of smoothing. You are correct in saying the dyno is modified, but it is modified by the software and based off a real curve.

Re: Up Close look
 

There are two possibilities here:

"anti-aliasing" is a feature used in graphics programs to smooth jagged or rough edges.
It is used by graphics editing programs, such as in Photo Shop, Corel Photo Paint, etc.

Presence of that does not necessarily indicate proof of cheating, as they may have had a legitmate reason to edit, such as deleting unwanted text, or something.


Or it could be a sign of the "lossiness" created by image compression software, such as JPEG.

All I find dubious is that certain features which are quite characteristic of this engine, are not present in some parts of the curve.

I do not buy the results, but let's assume they are correct why is the non-stock curve cuts off earlier. The actual work output is represented by the area under the curve. The new curve area appears to be smaller than stock.......

That can be due to a very simple matter of when they launched on the dyno.

Same as why the earlier cut-off at the top. Simply put that is when the tester took his foot off the gas.

Curious, anybody out there use SR before? I never have, but have always heard good things.

If this is true, then great! But you know what sucks? Change in power only comes in at 70mph+. That means, dialy driving and following speed limits would stay the same ;)

Read the following thread and see if you would like deal with SR

Do a seach on the www.rx7club.com. There are plenty of people having bad experience with them.

Good luck!

sr parts seem expensive as well.
$489 for the stock rear spoiler

Anyone have comments about the under-drive power pulleys? What could be so special?

WTF is wrong with you guys? Abel Ibara could come on here posting dyno sheets of his RX-8 intake, and you'd all scream FAKE! Ray Lockhead and SR has been around a LONG, LONG time. They were running 9's in their RX-7 before most had any idea what imports were all about.

Geez ...

Obviously somebody running this car needs to fake dyno sheets

I wouldn't trust Ray to feed my dog while I was out of town and trust him even less when money is involved.

Tim

I've bought one or two things from SR for my FD, and my personal dealings with him were quite satisfactory. Also, as BOOSTD7 has correctly pointed out, he has a long history of building and racing kick-ass RX7 drag cars.

That said, there have been a LOT of dissatisfied people on the RX7 forum who have had purchases that didn't go so well....so....who knows....


jds

I've bought a couple of parts and have had no problem with SR Motorsports. However, I questioned their dyno results for the 8 from the beginning. When I asked them how they got their dyno results, after seeing a picture of the 8 on a two-wheel drive dyno, they didn't reply. I asked how they were able to dyno the car on a two-wheel dyno when you have to use an AWD dyno in order to bypass the DSC and ABS fail-safe. The PCM has to sense the front wheels moving in order to distribute full power to the rear wheels.

Ray Locheed is no moron. He is smarter than most out there. I have bought several things from him. They always arrive quickly. He is always easy to get ahold of in an emergency. We just installed a brand new engine he built this last weekend in my friend Trixie's yellow 3rd gen RX-7. It was done great. The ports looked beautiful. We also installed the Power FC which he had tuned. The problem with this is that no 2 engines are alike. He always tunes on the rich side which pisses the RX-7 guys off because they expect to buy the fastest most perfectly tuned product for their car without having it tuned ON their car. Isn't going to happen. Yes there are alot of dissatisfied customers on the RX-7 forum. There are also people that hate Atkins rotary, Hurley, Rotary Performance, Pettit racing, Pineapple Racing, etc... You can't please everyone all the time and others you can't please at all no matter how hard you try.

He knows how to dyno that car. Yes it can be done on a 2 wheel dyno since several have done it. If one person gets 180 hp on a 2 wheel dyno and another person gets 184 hp on a 4 wheel dyno, where is the issue? When you show me someone who has done over 200 rwhp just solely based off the fact that they used an awd dyno, I'll believe that argument as factual rather than speculative. It isn't hard to trick the sensors. It is just much easier to do on a 4 wheel dyno.

Ray has nothing to prove to ANYONE here and he knows it. At least he is diginified to not bash anyone else for their ignorant comments against him. He just laughs those people off since they aren't worth the effort. He does look at this forum you know. If people don't want to deal with him than they probably aren't worth his time anyways. Service is a two way street and the customer isn't always right even though they may think so.

Well, THAT attitude is a good way to not get customers.

jds

PS: Yes, I realize that was rotarygod and not Ray...

I was in retail for many years. It is a realistic attitude and by absolutely no means what so ever unreasonable.

Well, if I am looking at two shops, and I walk in one and get a whiff of "Come in if you want, I don't give a *&^@, if you don't like what we say we don't want or need your business anyway," and I walk in the other and get that warm, fuzzy "customer first" sensation, which shop am I more likely to patronize?

(Answer: The one with the hottest secretary...oh stop it its a joke :D

Seriously, while every vendor has its share of detractors, I think you'll find far more people expressing their displeasure with SR's treatment of them than you will with Pettit, or KD Rotary, or Rotary Performance. While I can't vouch for the accuracy of those claims...my limited experiences have been positive as I stated....at the very least it seems that Ray hasn't exactly wowed a large number of people with his attitude. You may contrast that to Cam at Pettit, who usually goes out of his way to help people out, etc. I know both guys know their s***, and both make quality products that work...and yes, both guys charge too much :D ...but given the choice all things being equal I'd go to a place like Pettit because most of the people that go there end up feeling like they were treated well. I think if you took a poll that would not be the case with SR.

I think we've strayed off topic here...to try and reel it back in, I can't really see him faking a dyno sheet.

jds

I'm still not dissuaded from SR by the above arguments...no offense to anyone here, but I'll trust in-person commentary over the internet anyday.

From my personal experience, I can only speak of RX7.com and KDR. I cannot say anything bad about any of them, as each were great to deal with. When I get my next rotary powered car, I will only send it to KDR for major work, regardless of where I am in the country.

Xyntax:I don't even have average knowledge on dynoes, so I may be wrong, but that power curve is what you'll get in every gear. You see the increase about a third of the way down (what you think is 70mph), which'd be about 3000rpm or less. Every time you hit 3000rpm in any gear you'll get the extra power. The mph scale on the dyno reflects the gear they had the car in at the time, maybe 4th gear. Think of the 120mph mark as about 9000rpm, and count down from there; 110 mph'd be about 8000rpm, 100 mph'd be about 7000rpm etc.

Somebody who knows about this stuff, please correct me if I'm wrong.

I had thought of the above also...a dyno pull should only be in one gear that's ratio is closest to 1:1, I believe. Therefore, according to SR's dyno sheet, it should be more drivable in stop and go traffic than before.

In my case, Ray did indeed put one in my ass and didn't think twice after he knew it was beyond the time I could do a charge back. I bought an upgraded set of "twins" from him for my 7. Supposedly larger compressors, new components, etc, etc fro the 2300.00 I sent, along with the money for the PFC and commander. I didn't get them installed quickly since mine were fine, just thought I was getting a like new set with some power to boot. One turbo had some shaft play, more than my stock unit had on the primary. So I cal Ray, oh, it's okay, you should measure it with 43 psi of oil in with the bearings to take some of the play out. I go along with what he says cause I trust him about it. I get them on the car, smokers from the start on the primary. Call him back and let him know, he says we haven't done those type twins in over a year. Uh no idoit I bought these from you about 6 months ago, 2 months to long to charge it back you moron. I ask what canwe do to make it right...well Ray's a great guy and cares about customer service..he's going to offer me a set of 99's at a great price. Thanks Ray, mind giving me a cigarette with that ass pounding you just gave me. I take the unit off and send them to BNR to have a look. I'll cut Ray some slack in that the turbos are more than likely outsourced and not done in house. Well guess what we found out about my upgraded twins.....only upgrade was the blades were clipped, not even larger wheels or machined out interiors. Not to mention the thrust angle was off by 15 degrees and eating the bearings faster than Ray could spend the 2300 bucks I sent on beer and hotdogs at the 1/4 track where people think he's god. The secondary turbo lock nut on the end of the shaft was not even on. Great job Ray, someone as knowledgable as you let these piles of crap ship out of your rotary guru shop and left me out to dry. Yeah, it was 2 years ago now and since then I've gotten bad new 99 twins from Jesse Lau cheaper than dipshit Ray was going to give a shaft, I mean deal on. In my case, atleast, Ray's a crapbag who isn't worth stopping on the side of the road to help when his redneck ass is broke down in the rain.
I hope he does read this.

Tim

Meeeeeeooooowwww!:D

wow enough said tim ,i was going to order there new intake system ,iam having second thoughts

his stuff might make the HP he posts, just be on the careful side when dealing with this assbag. If his intake is making more than Chuck's, ask why when the design looks similar. Same goes with exhaust and other things Ray's claiming HP numbers on. See what others are claiming (greddy, Chuck, Borla, etc) and ask alot of questions to Ray and if you feel like he's answered them to your satisfaction, buy it from Ray and do your own HP test and see if he's telling the truth.

In my soapbox above, I meant to say that Jesse Lau hooked me up with a brand new set (0 miles) on the 99 spec turbos..not bad new set like mis-typed.

Tim

Tim Benton.... man that was some shit you went through.

That being said... OH MY GOD...ROTFL

just bumping it back up so people keep it in mind. Who do you trust? Ray claiming 14 rwhp or racing beat saying 3 to 4? My money's on racing beat. What would Jim gain by claiming his exhaust makes 10 less than a competitor? It's Christmas so I might have pulled over to help Ray if he was broken down on the side of the road...I said I MIGHT HAVE.
