Should I add a TURBO or SUPERCHARGER

[phatdad]

I run a Hahn and have had no problems for almost 6,000 .The only problem ive had is a egr code which did not effect how the car ran . Iam convinced the egr is bad this is not turbo related .Ive run my car at up to 15-16lbs of boost for short fun runs noooooooooooo problem but I also had Bob Stockum build the motor. The car is a ball and goes like the wind . Also u can use your strut bar I have the same one on my car.The only changes ive made is turning that boost control up and down .Irun around 11-12 lbs normally.Bob has great prices on everything u need and the expert help and advice is always free .AS a matter of fact I just called him on that egr question and he always make time for us dummies.

OK...so far Turbo seems to be the recommendation. Where's the supercharger guys?
AIRRIDE...I forgot that you were thinking about a turbo. We can get a long trailer, put both PT on it. Haul it behind my other BIG PT and camp out at Bob's for the week...The unfortunate part may be we'll both have stage IIIs by the time we come back.

You surprise me, OT. I thought with the upgraded electronics, the Whipples were running good these days. Still having problems?

Bob, my understanding was that the safe zone for the factory Cruiser engine was 6 psi (around 30 HP added) with an aftermarket turbo...no higher or you could be risking the engine. Is that right?

From what I remember, they said the stock engine wouldn't take much more than 200 hp.

What's a stage 3 upgrade on a PT that starts off NA?

Al, ... OC CRUISER, ran his bone stock PT automatic with the Hahn kit and a Ford probe IC he put on, at 8-9 psi for over a year with no problems. I kept warning him about hiking up the boost and he finally decided to do the lower end. In fact we built him a complete new engine starting with a new factory short block and then swapped them out when he brougt the car down.

It is this car you are riding in, in the video against a new GT turbo and that was two days before the origional engine came out! It also smoked a 97 Lincoln MK VIII LSC that same weekend. So I know his car will goooo!!

*** I still want you to know that the rods will break in these 2.4 engines at even low boost, ... if something else goes wrong!!

I got one of the early after-market-Ignitions and did not get a trigger module with it. When I called the tech dept, ... I was told I didn't need it! ... (now they are sold together) ... the PT cam sensor does not out put the nice "square-wave" the ignition needs to fire correctly. (the Neon does not need the trigger-module, ... cause it has a different sensor/ECU arrangement)

My test ride was only 3/4 miles from the house when in 3rd gear, at 4 psi and 4500 rpm the #3 rod broke and punched holes in the oil pan and both sides of the block, bent valves, munched the piston into pieces, broke the balance box and bent the crank!! ... Basicly a total loss of the engine. But remember the ignition was not fireing right. It rattled so hard and suddenly, that it was all over before I could lift my foot!! ... and I was ready for something, ... cause it just didn't sound right before I left the house. I went any way, cause we had to pick up Debbie's PT. Debbie was in the car with me, on that terrible evening, when it blew, ... we were going to pick up her PT, .... I had just installed the Hahn kit on! .... Talk about bad advertising!!! ... her's is still running fine. I talked to here last week and she is considering adding the IC and turning it up some more, ... but she will be doing the bottom end first!! Probably a complete engine like we did with Al's, ... so the down time is not so long!

Al's engine was tuned properly and kept on the rich side, ... so he had no complecations. I asked him if I could "test it out" against a new GT, .... so we could get a base line on Hahn vs Factory Turbo performance, ..... he said "it was mine if it blew " and I agreed.

The rods in the 2003 stock PTs, are no better than the early ones, ... just the GT/SRT-4 engines get the stronger rods.

Thanks for the questions!

No probs! But I DO wish I had known of the the Hahn turbo's release soon after the Whipple! I'm one of THE first to have a Whipple, but AGAIN like the versatility of Hahn's turbo!
Bob doesn't know it yet, but I'm comin' & wanting to (& actually following thru with) getting the port, polish & upgraded inards WITH the Whipple JUST to see if that'll be beneficial, so I can, if possible , add a nitros in the future!

Just for clairification, then, your answer to the question of whether the safe zone for the factory Cruiser engine (no heavy duty pieces added) is no more than 6 psi (around 30 HP added) with an aftermarket turbo is...yes. Thanks.

[LandHO]

like the versatility of Hahn's turbo

OVERTAKE, what do you mean by versatility? Are you referring to the ability to dial in more PSI easier? or the ability to go to stage II or IIIs

Thanks.

More efficient and no need to swap pullies for power...boost controller and dial it in.
