Hosrom, let it go buddy. There was a certain degree of kidding. You seem to be a pretty nice guy with good intentions but ease up a bit on giving advice on something you've never seen, tried, or done. I used to have a big problem with Eyal 951. We've had a few "spats" here and there. Now we rarely hear from the guy because he's too busy working on his car, trying out products, formulating his own opinion, and probably getting ready to kick my *** on the track now (I am scared = )). I, and a lot of other guys have a lot of respect for that. There's nothing wrong on giving an opinion but when your opinion is based on perception, not reality then it becomes an issue. In one breath you're asking the most elementary maintenance questions and in another your trying to tell someone else about the latest performance mod. Just like the information you pass along, just because you read it on this list or some vendor's web page doesn't mean it's true. Here's a good example:

"Most basic chips are set at 15psi, unless you contact John at Vitesse and tell him to customise chips at 18psi or so."

Vitesse chips are already set-up to run 18psi by adjusting the FQS. APE's are not set up to run a straight 15 psi. Guru's are set up to run 15 psi but Danno will gladly sell/burn you an 18psi set.

You make it well know that you don't do the work on your car (there's nothing wrong with that) and your car is basically stock (even though it seems to be the fastest one on earth) so it would help get a few guys off your back if you offered advice on something you have tried or have intimate knowledge of. That's all. Many newbies come here to ask questions from guys with experience, not opinions based on web site research. It's hard for these new guys to determine who has the experience and who doesn't. Don't make them spend hard earned cash based upon information that's inaccurate or hearsay. Don't post to a thread just to get another notch in your belt. No one likes to be sent on a wild goose chase. Like I said, nothing personal, you seem like a pretty nice guy with good intensions and there's nothing wrong with that .

Jermy: Your a pretty nice guy too, and yes i agree with you (and several others) that opinions are not based on information alone.

I do work on my car, but not touching anything to do with electronics at the moment (going through an interior restoration project myself). I have been working on 944's for 4 years now, the thing is, it's not 'simple' as it seems. What i mean is you guys in the US have access to such a wide variety of things (for a relatively good price) unlike here, especially on 944's where there are only 5~8 of them here in the country.

Anyway, i always try to 'dig' up information that would help me creat a 'list' of what i need. Which doesn't sound right, but honestly, between you and i, that is literally the only thing i got here. That's why i ask a ton of questions to various vendors to see what the outcome is and let it out here (which isn't ALWAYS good).

I was just trying to help out, not mislead (and sorry if i did). No harm done i hope

Jerermy: I just remembered something.

Just to show you how 'bad' things are here, i asked my porsche specialist regarding upgrading turbochargers and boost levels, i am not making this up at all, i am being truely honest here:

Q: What is the max boost i can run before needing an upgraded HG
A: You can run 1.4bar, after that a copper head gasket is needed. Over 1.4 with a copper HD, you can reach 2.0bar, that is when you need new bearings for your engine.

He has NO idea what-so-ever regarding a/f ratios and fuel grades for 'proper tuning', now you see why i search so much

P.s. HE was the floor man technician at our authorised porsche service center, now running his own busines

Please allow me to highlight the boost issue on the Vitesse Chips. AFM chips can exceed 15psi on pump gas, MAF chips and the ones sold with the kits are limited to 15psi on 93 octane. Please take a look at the "chips" section on the website, it explains what you can do with the AFM chips...

You're welcome Hosrom. BTW you're not alone
about the lack of knowledge on our cars. I think
I am the first person in my country to fiddle with
the 951 about five years ago. Unfortunately due
to work commitment abroad, I was unable to
continue my upgrading adventure till recently.
Yes, local Porsche mechanics here sucks too.
Thanks to fellow Rennlisters, I've learn alot
about our cars & whenever I have the time I'll
work on the car with the help from a mechanic
friend.

Hosrom,

When my car was stock I ran 15 psi all day long (on the street and track) without any head gasket issues. When I pulled the head for a rebuild, the gasket was perfect even though you could hear detonation with the chips I was running. The technodyne cars (Cervilli built) ran upwards of 25 psi all day long with an o-ringed wide fire and new stock studs. Right now I have a multi layered steel head gasket on my modded car and a wide fire on the stock car. The copper gaskets are old hat at this point and the MLS is the newer technology.

I "believe" the 951 communities puts more emphasis on putting on a mondo head gasket then getting a proper tune. Sometimes it makes me wonder if people really listen to whet their car's telling them. Personally I wasn't that impressed with the MLS gasket, but I have never had an issue with blowing head gaskets. Would I buy one again? I don't know at this point, but I wasn't overly comfortable with the way the gasket comes separated and you sort of hope that nothing overlaps when installing the head. Mine also didn't fit quite perfectly over the deck dowel pins. If you're planning on running upwards of 15psi I would suggest at least a wide fire gasket. IIRC, Rage2 made tons of power on his 2.5L with a stock head gasket. My personal opinion is that when you start hitting the 21 + psi range then you should start worrying about things like headlift/walk and cylinder pressure and possibly look into o-ringed heads (even though I am not a fan of it). 10 people will agree with me and 10 will disagree.

Head studs, well that's another story........

Aight im about to modify my car... its on stocke engine with 153k, runs perfect no problems. Im thinking 18psi vitesse chips with tial wg. By what ive seen this should get me around 300bhp/300lbs-ft. Would anyone recommend this or should i back off and get something like gurus chip set with 15psi and wg?

Jeremy Himsel

After putting all of the atermarket chips in my car and throwing it on the dyno, I have to recommend the Vitesse. The best HP, TQ, and drivability. With Vitesse chips you can run 15 ot 18 psi depending on what position you have the FQS on. The tial is a great chioce. The misinformation you have is unless you are running a 26/8 turbo you won't be close to 300 RWHP. Maybe 265 at 18 psi but that will be a stretch.

ztnedman1

I see. It doesnt really matter. I was more concerned with reliablity issues and if it should not be putting my engine through 18psi worth of stress. I want more power.... but i think im starting to lean more toawrds gurus kit, its only 300$ too.

shaheed

what you get is your own decision, the only advice i can give is to read what others have experienced dealing with products from other vendors and then make your decision accordingly.

Thanks jeremey and jchen for understanding.

Jchen: Yes, this place is just the way you explained it. Mechanics just service and do repairs, when it comes to tuning, 911's Boxster's and now Cayennes are their customers. No front engined watercooled car went through upgrades here. So, i tend to undertand and learn things from here at rennlist.
