Kelu 41-108 were the replacement, but they are a hotter plug than the original 41-102.
You maybe correct about the heat not been 8, but provably about a 7,

Kelu · « **Reply #101 on:** April 07, 2012, 07:14:27 PM »

You meant colder, not hotter, right?

HAMMER DOWN · « **Reply #102 on:** April 07, 2012, 07:46:28 PM »

No, the 41-102 are a colder plug then the 41-108.

Kelu

With all of the modded LNFs out there, why are you the first one to have issues like this? Someone much have similar set up or at least me moving similar amounts of air? Why are you getting your spark blown out and no one else is? I'm not saying your tuner is wrong, just not sure why you have this trouble and no one else.

Kelu · « **Reply #104 on:** April 07, 2012, 10:32:06 PM »

High rpm misfires of over 360 hp LNF is not so uncommon especially on stock engine. If you would take a look over the HPT tuners you will see many posts about this even with less power.
I look as the first one because on KP there are only few involved in tuning of their cars, except shabby and tazz. Generally people drop the car to the tuner and the tuner takes care of these aspects.

My explanation seems a little bit ridiculous by please ask doctor Dave, I bet my car that he encountered misfires when tuning cars with LNF with over 25psi at over 6000rpm.

I can attest to what you are saying. Ran into that on mine at high speed + high rpm.
Got that tuned out.
Still get an occasional one if I start driving before Lucy is fully warmed up but never once the temp hits 194F

wait kelu... you are running that giant comp huffer on a stock bottom end?

You are crazy man. Get the short block built asap so you can take advantage of the top end that turbo has!

Yes, my COMP turbo is way bigger than a GT35 on compressor side, but is reaching 26-27psi between 4500-4800rpm.
Short block might not be enough, I might need to rev higher, too many unknown things which I can't afford now because of the wedding.

For the moment I will work on small optimization to be able to finish top 4 in my races.

miller11386 · « **Reply #107 on:** May 09, 2012, 08:29:10 PM »

no doubt. Definitely need more rpm and stronger rods. Also a large WG if you run the smaller AR to keep the engine from having too much back pressure would be a plus... perhaps a tial 60mm?

elff · « **Reply #108 on:** May 09, 2012, 08:30:00 PM »

Yea going higher in boost is a recipe for disaster. Your engine will end up looking like Mondazback's

kennysabarese · « **Reply #109 on:** May 09, 2012, 08:56:42 PM »

Or just get a smaller turbo?

Gentleman Jack · « **Reply #110 on:** May 09, 2012, 10:08:45 PM »

Or just buy a Seat.

Kelu · « **Reply #111 on:** May 10, 2012, 03:33:29 PM »

F$ck Seat!!!!

I'm on a 48mm Tial. I have another engine in parts sitting, tuner offered awesome prices for internals and a good price and strong work on head. But:
1) I can't afford now
2) Afraid to go extreme with the engine (different cams) and than transform the car into a monster no so pleasant to drive on streets

Stop being a Sissy. I will accept the monetary excuse, but don't tell me its not street friendly. Streetablilty is all relative to what you can tolerate.

You can learn to drive it on the streets, or run a street tune and a max power tune.

Kelu · « **Reply #113 on:** May 10, 2012, 06:07:36 PM »

Buddy, without being a sissy

I saw so many real cases during so many years around me that convinced me to take some decisions which might seem weird at first look.

I saw street friendly cars with engine builds for 600-700hp and with a street tune which are nearly impossible to be driven on the street because:

- race clutch which was a nightmare on a bumper to bumper traffic
(these are real photos from my city)

http://stelapopa.unimedia.md/wp-content/gallery/trafic-infernal-bucuresti/trafic-bucuresti9.jpg

- exhaust is already at my upper limit with the most silence exhaust from Solo (can hold up to 450hp) and a screamer, I was stopped already 2-3 times by the police because of the sound and only luck and my nice behavior saved me for tickets and licence points

- insane costs for maintenance at each 3000 miles: do you are aware that I paid $150 for each set of spark plugs twice already? (you might say I could by them for 50$ from US but when you have an ECU tuner coming from Italy and you have only 2 days at your disposal and you can't afford to allow him to leave the country with unfinished tune) or 150$ for oil?

- suspension on bad roads, already payed $400 just to fix the damages because the exhaust dropped because of pot holes?

- have the car not operable because a stupid part broke and you have to wait 1-6 weeks delivery? (remember my case with broken turbo)

- pay everything on double prices in any case just because they see you have an exotic car and they think is a viper, corvette or porsche not a freaking Opel (I'm dumbass I completly debadged the car) and they label you Richie Rich?

I don't like to whine but I don't like being called a Sissy and I thought I should explain you why I have these "weirdo" ideas. I invite you to live in my place and than to call me a Sissy mister Race Boy

P.S. After more than 1 year I still think I did a mistake going big turbo instead of following my initial plan to keep engine stock, modify the exhaust manifold and use a 100-150hp nitrous shot for races.

elff · « **Reply #114 on:** May 10, 2012, 06:17:40 PM »

I can attest to the clutch.
The new Clutch I have grabs super quick and is awesome in 2nd, 3rd, 4th and 5th.
It also handles the power extremely well. Trust me, the past 2 weeks I have been working it.
It is also Killer to do a 1/4 mile with the way it starts.

But

IT BLOWS DONKEY BALLS when you are trying to start the car normally. The engagement area is so small and it grabs so quick. I am wondering how much of that might be the aluminum flywheel and if going back to a stock and thus heavier flywheel will help somewhat but allow me to retain the strength. I've gotten much better with it, but there is no way I will let my wife or the majority of my friends drive the car. Too much of a chance of them popping it and then jumping the sky into something in front of it.

Critterman · « **Reply #115 on:** May 10, 2012, 08:07:03 PM »

That will break in with use and heavy dumping episodes with the clutch

elff · « **Reply #116 on:** May 10, 2012, 08:29:00 PM »

Trust me, I am working on that.

Understandable kelu. I agree that race clutches can make a car a pain to drive. And :ol: at the romanian harassment squad. They would freak out if they heard a street race exhaust!

I know my car will be a monster with the twin clutch install bottom line is, it is your car. You need to be able to enjoy it. I am willing to put up with more than most in the drivability dept if I can have more power.

coming from the guy who was complaining about some coilovers? Miller, get your story straight! And don't forget, you have a second car (truck) to drive when all hell breaks loose.

And if you ever call Kelu a sissy again, I may have to put your hand in warm water while you sleep.

Kelu,
I got your back buddy! Nobody picks on Elffs little brother!

Kelu, i know that it will probably won't interest you, but it doesn;t hurt to know that. Megas read in the german forum that eds is about to release a big turbo upgrade with tune. he says it will have the Porsche GT2 wheel compressor .. !!!

Kelu · « **Reply #121 on:** May 11, 2012, 09:25:20 AM »

EDS is releasing a turbo kit for 2 years already

Let's see, Porsche GT2 has 530hp from 3.6L and twin turbos, that's 265hp per turbo or 291hp per 2L, why I should be interested?

Except the fact they are Variable Geometry Turbos and ridiculously expensive I don't think will be too appealing. I had enough by European Opel tuners.

But ... thanks for sharing
