anyone know the 3.2 chip thats good for 30hp?

[dickster]

i read a back issue (july 2001) of 911 & porsche world last night cause it had a track day feature.

it mentioned in the feature that john tipler had changed the chip in his 3.2 and gained 30hp! (exhaust system changed for H & S).

there was to be a future write up on this but i've never come accross it - anyone know what edition to look at or what chip it was?

keith s do you know, you work for the rag- let us in on it??

[juan ruiz]

You Guys are somoking some serious staff! 30HP from a Chip C'mon Lets get serious! 4 real in one of my EXPERIMENTS I had a CUSTOM MADE Chip From a Guru THEY GO FOR OVER $400 and you are lucky if you get half of that.

[ChrisBennet]

IMO. unless they list before and after rear wheel hp #'s anything more than 10-15hp is not too believable. You can gain lots of HP simply by using an inflated RWHP to flywheel HP conversion. For example, a 915 transmission car has about a 14% loss between the flywheel and rear wheels (217-14%=186RWHP). All a vender needs to do is use, say a 20% loss figure instead and viola', instant 16 HP gain! (233hp = 186RWHP / .80).
Skeptically yours,
Chris

Juan, calm down, buddy! Look at the post again.
The 30 hp chip was mentioned in 911 and Porsche World. Consider the source.

You Guys are somoking some serious staff!

its in their contracts! weed's hard to come by...........and our staff are pretty serious

no, seriously, i'm a sceptic too. i just came across this and i want to find the feature write up on the chip. then make my own mind up.

but hey, i'm not OPTOMISTIC or anything!!

LOL - you b*stard i know, i know, i just want to see for myself

Maybe I've misunderstood the post, but didn't it say a chip AND a Hayword & Scott custom exhaust?

I'd still say that 30 extra horsies sound too good to be true, but the exhaust alone is likely to be worth 10-20 hp.

[dickster]

mikkel

the feature said 30hp for the chip, but i know that tipler had an exhaust swap before the chip.

is he even still at the mag?? i haven't bought it for a while.

[juan ruiz]

Well I feel Much better I figure I had to Jump in
I have spend a lot $$ in Chips alone I must have 5 or 6 of those suckers aside from how fast I can go on top end they are pretty much the same.

juan,

lol

i appreciate that, i just want to read the feature! someone must have read it??

[Milu]

Giving an appetiser like that and then not following it up seems pretty typical for 911 & Porsche World.

30 hp from a chip alone? From 231 to 261 bhp? No chance!

The 3.2s had the first engine management computer on road going 911s. It was new technology and Porsche was a little conservative, but they didn't leave that much on the table.

Geof at AMD can prbably get you 10 bhp, with before and after measurement. I can't remember what conversion factor he uses but I think it's 16%. If he can't produce more than about 25 hp utilising hot film kits, bored throttle bodies, JR air filters with his skill and experience I can't believe 30 from a chip change.

That being said I have seen wild claims that also involved raising the rev limit to 7700!!! This was combined with MAF and was said to be an easy diy bolt on, in fairness to the tuner it was made very clear that it was not intended for standard road engines.

[juan ruiz]

The Same goes for those WONDER MAF KITS! I can tell you HORROR stories from their claims If you MUST have one PLEASE get it from a Reputable source 95% of are J U N K.some even have parts from other manufactors Like ford.

BUT If you Guys Find that WONER CHIP I can use another 30 HP!

[dickster]

milu,

excellent, you know geof? they seem like a good outfit at amd.

i have emailed the rag to see what happened to the feature. i'll email amd to see if they can shed some light.

juan,

i am one of your humble followers! funds allowing i wanna do the turbo route some day soon, and was hoping to use amd to fit a promotive (sp?) kit. (with their maf kit )

[dickster]

steve

yeah, we got 98 octane readily availble here.

still haven't located said article. emailed the mag but they never responded, typical.

[911jon]

Hey dickster....

Ever find this? I do remember the article, but cannot remember the chip manufacturer. I also recall that the H&S system proved very, very.....LOUD! lol

I only ask because one of the guys on the 3.2 Carrera board in the UK has suggested I get a chip from AmD; he had good experiences with them. I am interested. but would like to know of any downside, engine life etc. Like you, I use 98.5 Octane Optimax fuel. It is a very cheap 10-15bhp upgrade... quite tempting...

Thanks,

[dickster]

jon,

yeah, i should have revived this thread.

i got an email from john tippler no less (it was his car). i can't locate the email at work (i AM working here), perhaps i have it at home.

from my (limited) memory i believe he said that in his opinion the gain was from the exhaust and chip. personally i dont think i could live with that setup (you seen what h & s charge for that!).

as others have said above i should think you'll get 8-10hp from a new chip. i think amd take the time to dial it in properly to get the most out of it - thats probably where the real gains are. another 4hp with a sports silencer. (and 8hp on top of that if you've got a cat. and replace it with a presilencer).

i was all set to take my car to amd for setting up (suspension), and maybe have the hot wire kit fitted - but amd did not like the idea of their hot wire with a turbo (which is what i ultimately want) so i dropped the idea.

oh, btw, great magazine. do you know they never printed the article. can you believe that after the statements they'd made.

if i find that email i'll dig it out.............

[widebody911]

A shop here in Sacramento got 25hp out of a 3.2 with a UniChip and a custom 993 MAF setup. I drove the car, and it did seem a little peppier than a normal Carrera.

[dickster]

ok,found the email, heres how it went (thanks to john for replying) scroll down to read the first email, it confirms that AMD did the work:

"Richard

The whole thing was ambiguous, as the original rolling road comparisons when the exhaust was swapped suggested that power went up from 217bhp to 230bhp or so (I can't find the article but it was used in the mag) with the Hayward & Scott straight-thru exhaust. But AMD's rolling road claimed that it was only 217bhp when it first went on before the re-chip took place. After two or three hours work, the re-chip eventually lifted output to 242bhp. Of the two rolling roads, I suspect the one in Norwich wasn't giving the right reading after the exhaust was swapped. But on the other hand, the exhaust must have contributed some beneficial effect.
Without looking at the rolling road print-outs, my impression of the car's performance when the exhaust was fitted and when the re-chip was done is that that both things had an equal effect. So if we assume an overall gain of 25bhp, either one probably brought about a 12bhp increase.

And yes, it was the 217bhp cat car originally. It looks like Adrian Crawford only sources cars to special order now, which is a bit of a shame as I'd probably have had another one off him by now.

I've wonderd about the hot film or hotwire conversion. I think it's what comes on the 928 as standard. Bit too pricey at the moment, but I'd be quite interested. Like to hear more about your turbo plans.

john

thanks for the reply.

so you're not putting the 25hp increase down to the chip??

we have something in common in that we both bought cars from adrian crawford! i assume yours is also the lower powered usa spec engine, that originally came with a cat. - hence and as you said 217bhp??

i had mine dynoed as std and got 220bhp. i removed the cat. and replaced with a euro pre-silencer and got an extra 8hp. a dansk dual out silencer got me another 4hp, taking the total to 232hp - or what i thought i was getting when i bought the car!!

i was thinking of having the hotwire conversion done by amd, but thats on hold because i am looking into a very basic turbo setup (may as well make use of the low compression engine!!), which is not compatible.

i guess from what you are saying that i'd get an extra 10-12hp with the chip......mmmmm!!

i would definitely consider it after turboing, then amd can remap to suit.

i'll look out for the article.

thanks again

Hi Richard

Your email to Chris Horton at 911 and Porsche World has just been forwarded on to me, and the answer is, no, they havn't run the article yet ( over a year on!). So your query is quite timely in that it reminded Horton that it's still sitting in his pending tray!

In a nutshell, the re-chip did result in a smoother power deliver, as Geoff Everitt ironed out most of the flat spots, and the engine was free to rev more easily. So I suppose it was worthwhile - cost about £250. Power was lifted from 217bhp to 242bhp, although the AMD rolling road was at odds with one in Norwich which suggested I had 230bhp or so after fitting a Hayward and Scott exhaust system. AMD was sceptical that the exhaust made any difference at all, even with the cat removed.

Hope that answers your question. It will be nice if the article is used - not merely because it will earn me a few quid!

Regards,

John Tipler"

Wait, wait !! ......
We're mixing apples and oranges here as it relates to fuel quality.
USA and Europe use two different octane rating methods...the methods used by USA result in octane ratings typically 5 points lower than similar fuels in Europe.
Meaning? Euro 98 octane = US 93 octane..

Let's be careful out there....some guys are actually "using" this info

Does anyone know if the Uni-Chip will work on an 85' Carerra that has the Chip soldered in place in the DME box? I would seriously be interested in this since I don't "also" want to spring for a new DME unit. Thanks!

[Randy Webb]

The most powerful chip would be the "exhaust system" chip. I don't know that it will give 30 hp tho.
