Originally posted by forcefed7 First , I wish you would realize I never said anything about running 11psi. The boost level was almost three times that. I'm not asking you to believe me. I simply posted my dyno sheet to help/show what was possible with the correct tuning and parts selections. Looks as if I'm going to have to put together a AVI for all the nay sayer. Here's a dyno I did a few weeks ago. I had my purple computer on low. 571 rwhp with purple on low(11psi) I'd like to see that configuration. For the guy saying I am trash talking, fuck you. I am a true enthusiast, and if you were running around 2-bar as you are now stating, it is a more believeable graph, but I have yet to do the calculations at the higher PRs. The question of these numbers being produced with a center muffler and a PFS catback are also very shady, as these cut down the VE TREMENDOUSLY at higher pressures! Obviously it would be impossible for you to see those numbers with the 11psi pressure stated. For those of you who believe numbers like this blindly, without doing the proper research and calculation, good for you. I am a realist. |
I ran the calc for the new numbers.
All variables same as above, boost 30psi, netted approx 570rwhp. It is very highly dependant on the porting and VE%. The turbo you are using is very efficient, so you could see as high as 93-96% at hp peak. Please list the boost you ran for both runs, because as of now the hp/tq curves are not lining up. |
ummm i saw the car today. its real nice. forcefed7 is a cool guy i have a vid of one of his runs :)
|
Gordon, I am shocked that a center muffler (Borla XR-1..?) kills up to 50 rwhp.....At what point does the muffler become a big hinderance..?

E-Town Results
Thanks for posting the pics Greg.
it was nice to actually meet some of you guys (Vosko, Waynespeed). Just thought you guys might be getting bored so I thought I'd post my time slip, you know so you all can tell me how full of it I am. BTW I was even running a center muffler:p: |
another...
|
one last one...
Now I know some of you are not going to believe my numbers again, and suggest I run these times at another track. So I'll be at MIR next weekend. Thanks, Ray |
0h one more...I just wanted to back up the 10.3 run...
|
10.1
I ran 10.1 does this mean I'm making 600rwhp too :)
|
What is Forcefed7 running for tires to get 1.5 - 60' times???
Ken |
Damn Ray you were launching like a maniac good job dude:bigthumb: I will stop by M.I.R to see you make some pass's
catch ya there.... -Rikki |
Congrats on the 10.3 run Ray, but 135mph???? Ain't no 619rwhp in that motor. Hell, Demetrios is running 139mph and he's not making the power you say your making. Its not a big deal if you don't want anyone to know your setup or power your making. I know how much R&D it takes to get the right setup, but don't B.S. us. Just say you'd rather keep it to yourself.
Good luck this weekend. Ernie |
Questions on power
I have recieved alot of questions about the power that I'm making. I am choosing not to get in the middle of a heated discussion but I will answer the questions I recieved.
Turbo only 506 rwhp as measured on a dyno jet which is already posted on the forum somewhere. And at the track I spray a 50shot which NX advertises as adding 50rwhp. This is a total of 556rwhp. My car weighs 2750 with me in it. Best pass of the weekend was 10.13 at 138.5mph. These are just the facts and are not intended to call anyone a liar or start a argument. Just answer the questions of all the PM's I recieved in one shot without having to respond to all of them. My advice to any racer is you are better of keeping your dyno sheets to yourself as you do not see Ari, Ray Lochead, Abel or any other rotary racer posting dyno sheets on the list. Ray the only reason why I suggest this and ray please don't take this the wrong way as I like you as a friend and respect your dedication to racing and I know how hard it is to make races, but if you do not post your high hp numbers you will not have to defend yourself it just easier that way Ray good job representing the RX7 in the street class. When are we gonna get together and have that beer? |
Originally posted by gmonsen and here's the highest hp run i've ever seen posted before ray's run. its also 615 rwhp only its running NOS and boost in the high 20's or so. don't know exactly. maybe crispeed will comment sooner or later and tell us what he was running. the point is that crispeed is running an extreme port, race motor at extreme boost levels. not a street car. now, we have someone who pulls 615 rwhp with a street port, center muffler, and a pfs catback. the pfs catback is not even in the same class of catback as the apexi gt or other high flow catbacks. so, he's running hp that's a tie with the highest hp ever published on the forum with an extremely restrictive exhaust system. when you post those kind of numbers, its only natural that the more knowledgeable people are going to raise their eyebrows a lot. again, i just challenge ray to run the car on another dyno and give us another data reference point. having the lead tech for PFS run those numbers on the PFS dyno and producing numbers that are so extreme causes me to question how the PFS dyno is set up. maybe they have the altitude setting wrong? if by some chance they had the altitude set for mount rainier, it would raise (adjust) the numbers a lot to compensate for the higher (supposedly) altitude. this is an easy error to make. think about it. gordonhttps://www.rx7club.com/forum/attach...&postid=820669 The same car is daily driven at 20 psi minimum (W/G spring) on 93 octane where it have made 490 RWHP at that boost. crispeed 87 Rx-7 TII 9.204@150.47mph 2600lbs un-tubbed |

So my question for you guys making all this power is... how the hell are you doing it?! Everybody says "tuning", Ok, what exactly are we talking about? A/F and timing? Or are there some other aspects of tuning that don't get mentioned?

Not sure on the weekend
Not sure if I will be attending battle of the imports I'm trying to make some changes to the car before idrc in florida. But I may just run the current set up one more time.

congrats to you rotor_dee on your 10.10. 9s are close :)
Ernie, When the fuck are you going to be back and racing? |

Here is my latest dyno sheet:
http://www.ajc13b.com/472_2.jpg DISREGARD RPM READINGS! Boost reading are in absolute, so take 100kpa away and you get 170kpa which = around 26psi. Engine is a Cosmo 13B Turbo is a Garrett TA45, 72 a/r front with 68mm blade. 68mm exhaust blade with 1.05 exhaust housing. Not an MSD, Crane or any form of CDI to be seen near my car, coils are standard T2. Plugs are BUR9EQ lead and trail. Fuel is C16 There is NO NOS in my car in any way, shape or form. There is no artifical cooling of the intake charge ie water or methanol injection. Exhaust dumps next to the gearbox :D ECU is a Haltech E6K running the boost control and tuned by HITman. Timing is around 9 degrees lead and 7 trail. Changes either way cost HP and reducing split to 0 lost 10kw! Mixtures were set at around 11.8 to 12.0. Best ET to date is a 10.32 @ 133mph. Here is the timeslip: http://www.ajc13b.com/timeslip_10-32.jpg Diff ratio is 4.1 and gearbox is standard T2, far from perfect drag racing setup :D MPH is down and it seems the car hits a brick wall up top, this will be looked at. Max boost was 28psi on the track but this was only at the very top of 3rd gear. Gear changes are shocking with 0% throttle recorded during gear changes :D And have a listen here: www.fastrotor.com/ajc13b-10500rpm.mpg With me in it, the car weighs approx 2800lbs.... Sorry for the novel :D |
