Just got back from having the teener run on a Dyno.
Good and not as good as I expected. Was hoping for at least 100 Hp, didn't make it. This run was on a Mustang Dyno, allegedly a Dynojet Dyno reads from 12~15% higher. First the good. Runs were extremely consistent. the three runs printed pretty much right on top of each other. Torque was way up there above 95 tq from 3000 to 4500. with no real dips. HP numbers were very consistent with a nice smooth line from 2000 to over 4500 Now the bad Max HP was only read at 88 Hp and max torque was 100. If I add the 12-15% it comes to 100 Hp. But it is what it is. Build is 2056 D-jet, Heads by HAM RS+, 8.6 comp. Raby 9590 cam, SS HEs with Triad muffler. I Have adjusted the MPS to what seems to run best for this car. This car runs great and I just wanted to know what it was putting out, Not really planning to try to tune it for more power. Reliability is the key. and I am so far happy with that.

I don't care what is the best system, my problem is with the claim that a certain FI system alone adds horsepower which is total horse shit.
If you put an expensive FI system on a turd engine, you'll still have a turd engine. If you put an expensive FI system on a new engine with increased flow, cam, headers, etc, improvements of course you will have more horsepower. Duh! Tell you what, send me a system tuned to a stock 2056cc with a web#73 and I'll have 3 brand new identical engines ready to test on a Djet, SDS and your system. I'm serious, I'm already building 5 of these turn-key engines and they will be ready mid-summer. If you want to take it further I'll also have a 2.3 stroker performance engine that we could test with 44mm webers, and 46mm ITB's with SDS and your system. We would have to take up a collection for dyno time cash donations but I bet enough members will pony up for this event. |

So since you do this for a living: for a stock motor what would you recommend for a customer who wants a stock motor and is mindful of budjet? Since all the D-jet parts still have replacements available thanks to Jeff, Chris and to some extent Mark, what is the best bang for the buck? I don't think the German engineers left anything on the table for sure. For a non stock engine what would you recommend all things being equal and reliability and money no object and why? |

I'm building 5 Djets right now, 2056cc, KB pistons, web 73 full restoration, everything will be clean and rebuilt. 3 are for customers cars, two GA case engines are going into stock but I think I have the 4th one already sold. One engine will be 96mm AA pistons and cylinders, PO already had them. Never done this many of the same engine before. But... I'll build you whatever you want. Bring money. (IMG:style_emoticons/default/biggrin.gif) Best dyno accuracy is going to be an engine dyno. Less variability vs. chassis dynos. I'd throw a few $$ in the pot in favor or Mark's proposal. Even an engine dyno results are subjective at best and there's many factors that can skew results from temp, humidity, altitude to the big one...the operator. I've got a email out to dynapack, but I bet it's out of my budget range. Too bad the bike dyno is a different unit I could make money on that. |
