Congrats to Charles Blossom

What year PT cruiser is Charley racing, They didn`t make PT cruiser turbo convertible until 2005. Tom

Years ago, sage Dan Dvorak commented on a suddenly fast, former mid-range racer: he ain't smarter, his engine builder didn't get better....HE'S IN THE WRONG CLASS!

funny and true then.....and now

Thanks Dwight for the shortest,most descriptive reason we're in the boat we're in.

04 PT Turbo Conv is in the classification runs at 14.13 pounds--comp

Dwight and Ed:

Thank you for your responses. If you're right, why doesn't Bob Shaw own two of these Neons???

Maybe I'm dead wrong, but it seems to me that the fault, in this case, lies not within the factoring system (and therefore the classification,) but the amount of boost available to the engine. These turbocharged engines are factory-rated at the boost levels dictated, to give minimal warranty problems, and in certain instances, it is possible through engine parameter manipulation, (cam profile, fuel delivery rates, ignition timing, etc.) to increase boost levels with OEM equipment, which can increase power output, dramatically and concurrently. A 150 horsepower engine (normally-aspirated) when treated to 15 pounds of boost, becomes a 300-horsepower engine. Give it another 8 pounds of boost, and it picks up another 75 horsepower. This is not my opinion, but rather seems to be generally-accepted theory according to several books on turbocharging theory, by authoritative sources.

My contention is, Mr. Blossom has, in true hot rodding fashion, has found the combination that will produce horsepower far beyond what would be generated by that engine at factory boost levels. As I have said, this is only my opinion; I don't claim to have any information beyond that.

But, if I am correct, a tell-tale boost gauge placed on the engine by NHRA, would go a long way toward rectifying this problem without resorting to re-factoring the engine. All it takes is a vacuum line and a gauge. But NHRA hasn't seemed to be pro-actve in pursuing this path... Surprise!!!

Food for thought....

I dont think Bob is a mopar guy.

Wrong They made them in 2004 All convertibles were turbocharged

[bill dedman]

And, shame on me for calling Mr. Blossom's PT Cruiser a Neon... I THINK the Neon's SRT turbo engine is a more powerful version of the OHC Mopar 4-cylinder than what goes (went?) into the PT Cruiser.

Sorry for any confusion....

Wrong,

Just like all Cruiser's you could get them with or without the turbo. The confusion is that ALL the GT models came with a 220hp turbo motor but you could all Cruiser's with the FI 2.4, 2.4 turbo/180hp or the 2.4 turbo /220hp (gt version) and the SRT Neon was 230hp, I believe.

I was told that all the turbo motors were the same but with different computer parameters.

Girlfriend has a convertible with standard engine and I have the 180hp turbo 4 door. love it by the way!
