PT turbo

Anybody race one of these yet? I have driven a few around the lot, but you can't get speed in a dealership lot when your trying not to let the customer see you. The other guys that have taken them out for drives say they've got some ***** once your get up in the RPMs. Just wonderin if anyone has come across one.

I raced one at the track with my 89 Firebird, 2.8L V6, he won the race... But I wasn't that impressed, If I would had raced him with my old GTA with a 305 TPI, I would have raped him...

I don't know, but it wasn't that fast... But we only have a 1/8 mile track so maybe I'm wrong... But he was passing me about like my friend's 2002 Sunfire... So it's not that fast hehehe....

215hp@5000 and 245ftlb@3600

If he was an automatic he's not using the power like it could be used. I'd love to see what kinda 1/4 mile times a stock PT Turbo 5-speed would make. The trans guy here at the dealership said it's got the same 5 speed that's in the SRT-4. Basically this is a SRT-4 with a heavier body. We all know those SRT-4's can haul ***.

I would hope so, but a race from 60+ would be close. Turbo's love RPM's.

If I remember correctly, it was an automatic transmission. Well, it was ONLY 1/8 mile, maybe that's why he wasn't that fast, but that day I happened to race against Honda Civic SI, Golf VR6, and other stuff like that, and he was in the slowest that day, except me with a 2.8 bird.

it's not like turbos don't spool till you hit 60mph or anything

many stock turbos start boosting really early

but lets take for instance your situation
you say the car by 60 isn't doing much from the turbo yet

so from 0-60 the car is running mostly N/A

the car would be a beast from there on out prolly able to take Ls1's and stuff stock after that point being it is able to make up the difference from N/A to turbo in that short of a time it would need to really haul *****

OR

the turbos do really make a difference even fairly early on

heck there are a few guys I know of who run the boost and stick yet still pull much better 60's then I do
much better 330 times
much better 1/8 times

why?
cause it doesn't take 60mph to reach boost
generally not too far into first is full boost achieved

That, and if you know how to boost your motor with a 5 spd, you'll be a bit faster. Auto's in turbo cars kinda suck (unless specifically modified). I hear the PT turbo runs HIGH 14's low 15's (with a good driver).

Here's the place where I got the 215hp

http://www.automotive.com/reviews/17...o/buyersguide/

Here's another

http://www.new-cars.com/2004/2004-ch...t-cruiser.html

First...we're talking stock turbo cars...so low boost is out of the question. Most stock cars I've seen have a lot of turbo lag. Yes, most stock turbo's are small and spool faster than bigger turbo's, but they aren't set up that way from the factory.

Second...if he really raced a PT turbo and not a regular PT and he didn't get spanked...it was an automatic and maybe a inexperienced driver. Let alone that fact that it was 1/8 mile.

I have a lot of buddies into turbo cars, and I always get them off the line and up to 60...if we keep going, they catch up. Mind you, these are stock setups running no more than 8psi.

Turbo's run off exhaust and vaccume, so it's obvious that the more RPMs (60 mph) will make boost come on faster than ilde. Your not in boost at 60 unless your on the gas...which creates vaccume...and that closes the wastegate...creating instant boost. The amount of boost is related to exhaust flow, and that is higher at higher RPMs (60 mph)

Obviously doesn't know how to drive. It is incredibly easy to drive a automatic with a turbo. All you do is load it up against the converter and you're already making boost. You are only limited by traction on the launch.

An automatic with a turbo will out 60' a stick car 9 out of 10 times. Automatics loose on the big end because of extra power lost in the drivetrain. But locking the converter will gain some of that back.

I watched a 5spd one at the track run a 15.3 with just a fart can so they arent all that fast, but anything with a turbo can be made fast farely easily so you gotta watch out. All L98's should be able to smoke them and the 5spd LB9's(better cam) should be able to beat them or at least hand with them.

well you get what you pay for right? Most people would opt for the neon srt-4 if they wanted to go faster. so most of the people that buy them probably aren't looking for 3rd gens to go race right? Nevertheless, it produces decent #s and you got to give it that, ugly or not.

Honestly, I respect every car on the road. Because they can cause harm or death. Vechiles are faster then you and I. So i respect them. But i think the PT Cruiser is ugly and not my taste..... Big Deal... Doesnt mean i still respect tho, due to what it can do. IMO i thinks it ugly AND boring. Not my taste. BUt some other people talk about them 80s Camaros and how Hilly Billy and White trash theyre. I ignore those Fools, because i kno its one of the most greatest times in your life to sit in one of the M*llet mobiles. Its one of my fav experiences(driving a 3rd gen), and always will be. But those PT Cruiser can say the same about me. Call me a fool For whatever for ownin a Camaro.

My camaro isn't exactly mint. So when i got a chance to sit in a 35th SS, i wish i wasn't still driving my 3rd gen, but hey, its a good bang for the buck. The reason i still keep my head up with my "not mint 3rd gen" is because i know its a good piece of american history and therefore like you said, who cares whether that guy next to me thinks i'm... you know. Pretty much any car is faster than me, well maybe i can outrun a daihatsu hi-jet on a hill on a bike up to 30, so no matter what car it is, gotta have some respect because they sure can mess you up!

that kinda depends on the car
there are quite a few cars out there that stock yes have some lag. your not going to get away from it but they able still able to make full boost genearlly by about 2500-3000rpms it seems
with boost starting a little ealier then that
what is your def of lots of turbo lag?


I have a lot of buddies into turbo cars, and I always get them off the line and up to 60...if we keep going, they catch up. Mind you, these are stock setups running no more than 8psi.
too many things going on to just blame that on the turbo
first FWD, AWD, RWD?
is it a motor setup for high revs?
if so genearlly they can't launch well due to the high rpms they need to launch at which sometimes can make them lose off th line
there are other things to think abuot also



Turbo's run off exhaust and vaccume, so it's obvious that the more RPMs (60 mph) will make boost come on faster than ilde. Your not in boost at 60 unless your on the gas...which creates vaccume...and that closes the wastegate...creating instant boost. The amount of boost is related to exhaust flow, and that is higher at higher RPMs (60 mph)
that still doesn't mean that they won't be running boost untill 60 mph

yes rpms do mean more exhuast flow and a chance to build more boost

but by the time the car should be at 60 mph he should have been at full boost for sometime

Hey guys, I thought I'd shed some light on the PT Turbo topic since I happen to own an '04 - I'm normally lurking this forum checking out info for my wife's '92 Camaro RS 3.1L.

Anyway....say what you will about the looks of the car, it won't bother me - we all have our own tastes (Camaro vs Firbird debates just kill me, but I digress). Like I said, I have an '04 PT Cruiser Turbo Lite, which means it did not start life as a PT GT but rather a 180HP version of the GT's 220HP engine. Until I did the Mopar Stage 1 turbo upgrade that is, which gives either engine a nice 235-240HP. I've got a custom CAI/Uppercharge intake that gives me better throttle response and definitely some more power. My best 1/4 run so far has been a 14.87 @ 90.5mph (ambient temp around 90F here in SoCal). This on my street tires (Dunlop SP 9000 - 225/45ZR-17) at about 34psi. And yes, I have an automatic.

Turbo lag is almost non existant - nail the go pedal and it takes maybe a half second for the front tires to break loose. Same from a 20mph roll - yep, the tires will indeed break loose.

A friend of mine is running a dual stage boost controller in his PT (also an automatic) and I've seen him run a 14.2 1/4 (don't recall his trap speed) and I must say it's great fun eating Mustang GT's with these things (older 5.0L and newer 4.6L GTs, either way). To me, that's the beauty of this car.....nobody expects it to run like it does! The looks on losers faces are just priceless! By the way, traction can be a real bugger with these cars, so it seems the 5sp guys kinda struggle getting them to hook up.

Just thought I'd share, and I wish the wife's 92 RS was this fast, but then again I wish the PT handled like the Camaro!!!

They must all be stock then. The guys I hang out with at the track are almost all running the Stage 1 upgrade. The 15.5 you mention sounds dead on for a stock GT. It's just so darn easy to do the Stage 1 upgrade and knock 7/10ths off your time, then add a boost controller for a couple hundred bucks and shave another 1/2 second.

By the way, if any of you guys are in SoCal and regularly go to the street legal drag days at California Speedway in Fontana, the PTs out there lately have been us. Stop by and say hello....we should have 4 or 5 out there this weekend, 7/31/04

Not really, many MANY other factors go into when the turbo spools and how much boost it efficiently puts out.

True, but....unless setup otherwise...turbo cars don't a good bottom end. All factory turbo cars I've seen are this way. They aren't anything compared to my 350TPI out of the hole, but their power is up in the RPM's. Actually...most cars make most their power up in the RPM's. Look at nascar...they could make good mid power and rev lower to save stress...but they have more power potential up high. It's what a stall convertor is for also. Get's your engine revving...deeper into the power band. It's why a manual is more fun for some people...you have more control over where you are in the power band.

I guess that's why turbo buicks don't rev over 5200-5500, because they make all the power up top

A turbo buick properly launched will pull a holeshot on your L98.

You're obviously confusing ALL turbo motors with high revving jap motors...

Comparing NASCAR motors, which are N/A, really holds no water when comparing it to a turbo motor. I could rev my turbo motor in first gear at light throttle at 5K rpms yet it won't much much boost..why? It's a little thing called load. Go try revving a turbo motor while in neutral and tell me how much boost you get Also NASCAR is a circle track where they NEED the power up top due to the type of racing they do...not really hard to realize that.

Oh and using little German motors as your basis doesn't count either..the 1.8T or any other motor like it is junk too (not saying you were, just throwing in a little jab at those terrible motors).

Not trying to be an ******* or anything, just trying to clear up some misconceptions.

Mind you I'm still learning...everything I read here, books, everywhere is something new. My theories come from my experience coupled with my thought process. Sometimes the thought process doesn't lead me in the right dirrection.

My turbo experience is with Jap motors...so the experience is limited. I have always loved the GN motor...and have thought of putting one in my GTA.

I do know neutral revving on a turbo car doesn't create boost. But if you put the engine in a high rev the put load to it...my assumption is that is if you rev, drop the clutch, then boost will quickly come.

Turbos are something i want to learn more and more about.
