Euro S race car supercharged

Three Wheelin'
With the 5.0 hybrids putting about 300 hp to the rear wheels, is the extra cost, additional weight and the potential for flirting with disaster worth an additional 50 hp? I don't know the answer but thought it an interesting issue to toss around.

I tried to do the 5l hybrid 3 years ago and had some problems with it. Now looking at cost and TIME I will definetely never do the 5.0l again. This took me 4 hours to install everything (you can do the install and go to the dyno the same day !!!) and if I have any problems at the track I can come back to my original set up in 20mn.

WHat class has this put you in Jean-Louis?
BTW - we met in 2000 at the dyno day in IL, where you trailered your grey race car down with your wife.

Brendan I remember we met at the Joliet dyno and at Michael also, for the class this is another story, right now I am concentrated on the HP gain and go to Road America to really check the car.

Sounds great. I have to get to the track, in SOMETHING.

I know that same Orginizations will not allow forced cars, unless they are built that way from the factory.
IE - With ASA/Pro Auto (my old club - no longer working for them) if I forced my shark I could not race in any big bore race class, (anything over 4.0L) because it didnt come stock like that. No matter what class - but for ***** out street car track days. Acceptable.

Dyno Compare - Supercharged vs. Chevy 928...
I superimposed as best I could the Dyno I had done last friday with your Supercharged 928. I'm not sure at low RPM's how accurate the comparison is, but at mid to higher RPM's the comparison sould be fairly accurate.
As you can see your 928 has more horsepower and torque than my 6.3 litre Chevy normally aspirated, and as all 928 engines the power comes on at higher RPM's. The Chevy offers much more mid range power which is likely to be felt without driving the engine very hard. In fact the Chevy loses power after mid-range... this would have less of a top end... the supercharged 928 should have a much better top speed...

You will be a Monster now at the PCA events - you have learned to conserve your speed thru the corners with the lower-output setup, now with more straight line acceleration too - you'll be wicked!
Beef up you oil separator/catch can system if you haven't already.
SMTCapeCod - The MSD Boost Sensitive timing retard products will not work with the early 928 ignition. We have transistorized ignition, not the capacitive discharge ignition they are looking for, and the MSD box is designed for primary voltages of 12 to 14v, where we are running about 9.6 V after the ballast resistors (early cars). I cannot say whether the MSD product would or would not work on later 928 ignitions, I am just speaking to the early 928 16v ignition.

You are indeed correct about the 928 not being compatible with the MSD boost retard boxes. Mark installed two on his turbo '86, according the direct instruction from MSD and yet still fried both of them. I have two on my shelf but will nto be using it on the 928. Its really too bad casue they are an excellent product.

very impressive for such little boost. looks like 320 ave rear wheel hp over the operational range of 4500 to 6000rpm. not bad. Like an older GT3 cup car!

nah, you can run in most all racing groups in a top class with any kind of blower. in ITE, its anything goes, in PCA, you get tossed into the top group with the fastest cars in the world, due to displacement and it being turboed. POC, same thing. TCRA, also top class and displacement .
the good news, get some trick intercooler and you get that think in the 400hp range quick. maybe some adjustment button for on demand extra boost!

Malibu, there's something wrong with your dyno chart since the curves don't intersect at 5252. Also, you you have 1.6L (34%) more displacement than the N/A Euro, but that only gives you (less than) 28hp (10%) more hp.
Jean-Louis, that's a pretty cool project. Do you plan on incresing the boost, or running it on straight 93?

Hi if you have not talked to Carl about his windage tray/seperator it might be a good idea to find out it could save the engine, in the turns, Goodluck, Stan

This is Rob's stroker
1985 928SS, AT Platinum Metallic, 440 RFPT/360 RWHP
Maybe you could compare you dyno graphs with his. Would a better intake wake up the top end of your 383? It works for the 928 strokers.
