Just want you to give me an answer to this :
Christian Pickering's S15 which runs a HKS - 3037S FULL complete turbo kit HKS 2.2L, stroker,liners,step 3 head system, etc you name it. Power FC D-jetro 1.5 bar boost. Makes 400rwhp ( just a tad less ) And now you guys are telling me a 2871R makes that much with a shit engine and sweet fuck all boost? really, you american's need to wake up. you guy's arn't on top of the world these days!!

2871R s do not make 400 WHP on real dynos - and in Australia they only use real dynos - IE Dyno Dynamics -
No dynojets down there- So no 400 whp - makes perfect sense - you can only pull that crap on mild built srs on inlfated DJ numbers

We run mustang AWD dynos in the south.
Theres no way your getting those numbers... at lest not on a Mustang, Dyno Dynamics. s15 turbo, 264 cams, tuned power fc, =250-260 2871r .64, 264 cams, tuned AEM =330-340 these numbers are that ive seen personally. Mustang, Dyno Dynamics dynos = hart breakers Dyno Jet = bragging |

Its better to compare track times than dyno #s. At my school we have two of the SAME EXACT dynos, and one read 10hp higher. So i dont know whos right, but dyno numbers can vary like stated above.

im not saying anything good or bad about teambadrun.
just my personal experiance. i agree with rex2rx. i have seen a 35r audi s4, on neo gen tires with 425hp(mustang dyno) walk on a 600+hp(dynojet) lightning...on drag slicks. |

you are hard headed, that is all.
I have probably talked to Pete Liebig way more than you, and you actually live in Australia. So many points have been brought up about you that kinda goes to show your not a stand up guy. I ought to ask Pete about you just to see what he has to say about you.... I will agree with you that the eddy current dynos such as dyno dynamics simulate road load way better than a dynojet can therefor eddy current dynos are the best to tune on, however I dont think that their method of figuring hp is right. How can you figure hp when extra load is being added to the engine? Horse power is simply how many watts could be generated if your car were hooked up to a generator. To me, that is how dynojet figures is and that is what I consider correct. Its funny people call eddy current dynos heart breakers and dyno jets "inflated" This argument can go on forever but which one is your real numbers? I feel that dyno jet is the right way because that was the way hp was figured when the unit of measurement was first introduced. Now just that eddy current dynos are a newer better way to tune your car does not mean that the rules to how hp is figured should be re written. I think if you really want to know how much power your car makes, tune it on a eddy current dyno, and then run it on a dyno jet. Or better yet, hook your car up to a freaken generator and make some electric power and figure it from there (which is basicially what you doing when you strap down on a dyno jet anyways). |

But you've said before that dyno dynamics are underrated.

I really don't think a Dynojet is very accurate for real HP. I think you are referring to a post that SteveShadows said the Dyno Dynamics were reading low because something about the barrometric pressure was set wrong or something like that on his friend Jordan's car....
In general I think on a DynoJet 410 -420 with ProCams and IM and EXH manis is possible, but really.... on DynoDynamics maybe 20% less.... GT2871R's are not gods gift or anything its just a cheap alternative... I must agree though real men run GT30's and 35's and I ain't got the money or the balls to run something like that on the track or even the streets unless I have $$$$$$$ for brakes and engine work. Going fast is easy, slowing down and controlling it is the hard part...

haha, ^^^^ spool time suffers enough with the 2871 .86 though. I couldnt imagine the 35r! I would have to run a ka or rb before I would go that rout. I really would like more low end and next turbo will be a smaller one. Probably just a stock s15 turbo or ill change mine around to a 28rs.
You track your car though right? Id say its easy enough for you to stay up in the revs easy enough you could run a 35r. Some of these parking lots will throw such a tight corner in on me my rpms dip a little too low when controlling myself around it. |

Fighting about hp is retarded anyway.
For me, a dyno chart represents my usable powerband and the dyno acts as tuning assistance. If I felt compelled enough to "prove" my car's abilities to anyone, i'd take it to the track. Suck at driving or not, the trap speed tells a better tale than any dyno readout ever will. |

Wow Teambadrun you sure do seem to know your turbo's hahahaha. I am going to have to disagree with you completely on your ideas of the s15 t28 turbo though and definately agree with smelly240 on this one. I have one on my s14 Sr with HKS 256/264 cams running 15psi of boost and dyno'd 296rwhp. I have the dyno sheet to prove it incase you dont believe me, just let me know and I will be more then happy to post it. This dyno is at my school (School of Automotive Machinists in Houston TX). This dyno has also been proven many times to read either dead on or a little lower then most other dynos across the country. I will be returning to run at 18psi to see what max rwhp I can get out of this set-up. Just my 2 cents on the subject.
Thanx, Cameron |

just so everyone knows how i feel...
teambadrun is a jerk... i wish he'd just go back to the forums in aus (oh wait hes been banned from them all with like 40 accounts for scamming). Then he tried to namedrop like we care - and when he gets called out has a childish remark. On the other hand, I believe that a gt35r is going to be a bit big for most people tracking their cars... a 30r is probably more suited.

Ok m8 get ur story straight about the 15 turbines. I'm in japan so i don't have "good forgiving dyno's" and my buddy is pushing just under 350rwhp. not at the crank but at the wheels. And that's at 1.2bar. and 264 cams. I don't know about the 2871r but it's bigger than the 15 turbine so i'd assume that 400hp is reachable. And for silvia13t14 i'd get the 2871r. That's what i'm going to get and i've heard nothing but good things about these turbos and they're response.

Ok now I can tell you first hand what is the difference abot these dynos.... and dyno jets just should go home. Cause its so bs....
I drove my ass down to LA yes LA! Just to tune with Steve and I live in Norcal. Here are the REAL dyno numbers with HKS 264 Step1 and GT2871R To tell you the truth I was expecting under 300HP at 16.5 psi.... Crazy! Steve is the man and I will put this out, I don't think there is another person that tunes a car as methodically and detailed as Steve. Amazing and the car, I must say its neck snapping fast..... Seriously... Look at the TQ numbers.... At 4k I have 200Ft-Lbs of torque MY GOD!!!

I'd rock the 35R only at the drag strip or if you need a freeway monster....really don't need that kind of power for drifting.
If you need tons of power, but still decent response, I'd suggest a forced performance HTA30R. The best of both worlds...awesome top end + good response. |

Thanks Ken,
again the DD is a little low, and with 20 PSI and some 100 octane we coulod pull the car up to 350 whp range, which is close to 400 on dj. We can work out a discounted rate for another session if you ever get the bug Finally getting some 2871R cars that are put together right with the right quality parts and gear so that I can just plug in and tune it instead of spending the whole session trying to fix basic SR technical issues that the engine installer did not address (and I have had some MAJOR WELL KNOWN shop's work that is just utter crap and garbage come through). Just FYI on this whole GT35R vs. 2871R My GT3076R spools up only 500 rpms later than a 2871R .64 and about the same as a 2871R .86 in almost evey case study I have done. Again it's all about BALANCE and the proper set of parts + the right kind of tuning.
