Unbelievable I took my piping off Monday to clean out.While I had it apart I made one of those DIY pressure testers and Im glad I did.For som reason at 30 psi my intercooler would only have a 10psi But I could not see any leak.
I mixed up some soapy water and boom big bubbles on each side.Come to find out who ever had the intercooler before me drilled right through the mounting block into the side tanks.:madThats 4 5/16 holes 2 on each sideOver a one inch hole:mad I had to pump almost 57 psi to have 32 psi.Well My friend Lenny fixed me up cut off blocks closed holes and welded block all the way around.

Those of you who where at the track rental remember when I turned the boost up I went slower and my inlet air temp were high this is why.Andreas(from PPF)has been helping me as I contacted him on high inlet temps THANKS ANDREAS:buttrock.I just happen to stumble across the leak.
Over 2 years this was like this The original Lil 2.8 might still be alive:(
and I might have made over 1000 whp well there is always winter for the 1000 mark.


Im expecting some good times at the track rental monday:buttrock:buttrock

Un-freaking-believable! :lol

Glad to hear you were able to fix the issue!

Looks like I'm going to be heading down by myself on Sunday night. :(

Thats crazy!!! Well hopefully now you can go even faster. Cant wait for updates from the track.

that is a perfect example why I am not a big fan of using pre-owned parts...
I am sure alot of pre-owned parts are fine, I just simply would not chance it..
Good catch...... Ulysses..
Should make for a nice improvement..

WOW... Glad you found this...

W0W that is a huge hole, damn the turbo must have been way over speeding to compensate for the pressure loss. :eek:
Good thing you found it, the car must feel quite a bit different now:evil2

Holy crap that is a big pressure drop with holes that large.

And I thought that WOOOSH sound was you going by sooooo fast. going stealth FTW. LOL have a good outing. ///J.T.///

Good catch! Its insane that your car was so fast with those holes in the intercooler :eek: I cant wait to see what it does on monday :buttrock

Un-freaking-believable! :lol

W0W that is a huge hole, damn the turbo must have been way over speeding to compensate for the pressure loss. :eek:
Good thing you found it, the car must feel quite a bit different now:evil2Yes it was way over speeding and the air was getting pretty darn hot.
Roads are wet have not drove it yet 1 year of setings down the drain glad there is a test and tune.

And I thought that WOOOSH sound was you going by sooooo fast. going stealth FTW. LOL have a good outing. ///J.T.///
Not fast enough my friend......Not fast enough

were you putting down 996 with that hole present????


if you were, then your going to making ALOT more power don you think?


edit: not ALOT more power, but a decent amount?

doh...

We both knew that all I can say is PUDDIN
:rofl:

I was busting his chops when I got back and was telling him that he's afraid. He gave me a look and said "Whatever cuz..." :lol We all gave him a hard time but no avail. Even Jarek said give me your car and I will run a 9 for you...:lol

Oh well, hopefully next time...

Wowzer's! At least you finally caught it. 9's for sure! ;)

Whooley shit! That awesome you fixed it, just in time! Decent boost leak numbers in the past though....

Donovan

DOH...:banghead::smash:rock:
Glad it's back in good form. Can't wait to see stuff from the track rental.

I am so happy because with the glass half full, this means that your car is going to be an ABSOLUTE MONSTER AT MIR!!!!!!!!!!!!!!!
:buttrock :buttrock :buttrock :buttrock

Ya learn something new everyday.


Congrats on your find. This is just experience my friend


Also thanks for sharing this information so quickly....someone else will probably elimate this issue or quickly troubleshoot a IC issue because of this thread


Thanks again CC

wow. Glad you caught that!

Good lord!!! So you made 996rwhp with 4 big holes drilled in your intercooler!!?! :eek:

Yep Im wondering also what would have been the outcome with out the leak.
We thought the turbo and all the pulls just made inlets air that hot.Thank goodness the dyno runs are short when I tried higher boost at the track third and fourth got real hot.I can only wonder what boost the turbo was actually putting out to get 30psi on the dyno. I will dyno again after race season. I still want the 1000whp:evil2

Incredible. The car will be a whole different animal now, great news Ulysses. :)

Time for a new dyno!

I actually like finding problem like this :D B/c when they are fixed you know it will be that much better :buttrock

Good luck, I can't wait to see the drag times!

Hope it dries up! You have a lot of tuning to do! :eek:

Sweet Cardcounter! Are you going to redyno before hitting the strip Monday? Moreso, will you need to tweak the tune or should it be fine?

ooooo it's so good to hear your voice again!;)

p.s. will you please go run a 9 on monday!!! call ya then! k thanks bye!:D

Good catch! Its insane that your car was so fast with those holes in the intercooler :eek: I cant wait to see what it does on monday :buttrockWhat worries me now is traction and parts breakage

Hope it dries up! You have a lot of tuning to do! :eek:
Sweet Cardcounter! Are you going to redyno before hitting the strip Monday? Moreso, will you need to tweak the tune or should it be fine?I can get it with a couple third gear pulls.

ooooo it's so good to hear your voice again!;)

p.s. will you please go run a 9 on monday!!! call ya then! k thanks bye!:DHey dont you live in Md:D

Theres a dyno night on the 17th in college park if you wanna go. Show up some supras :buttrock

So does this mean you will have to retune it?

Thats amazing...996 with massive boost leaks,,,,

wow!! gald you found that out. I'll see you on monday were i can finally return your t-hooks that i borrowed forever ago :lol

wow ulysses thats a sizable leak - good that you found it. your iat should come down, assuringly, and that is never a bad thing! anxious to see how that changes how the car performs! best of luck!

Hahhaha the M52 makes teh ultimate powar all the while with holes in it's charge piping!!! Muahahhaa.

Nice sig Jon!

wow!! Thats fricking awesome that you ran 10s and 141 mph with that huge hole!! nice one ulysees... cant wait to see the fully breathing lil 2.8 in action !!!!

well, you need a new intercooler anyway

wow, unbeliveable!

you do realize your car is going to be a completely different animal now right? Andrew had the same issue last year, after he fixed it, it was a totaly different beast.

cant wait to see how the lil2.8 does now

Wow, owned by 4 holes. 996whp with big leaks? No offense, but pressure testing is the first thing you should have done, esp when running over 15psi. Lots of the BOV's I've tested will leak over 20psi due to the stock spring. My original tester uses a valve stem like that with a (free) gauge next to it. It lets you test things gently if needed, as well as check for long-term tiny leaks. BTW you should test your DP and manifold as well.

Used bar/plate intercooler = $200+
Making 996whp with serious boost leak = $$$$$
Being owned with a $3 pressure tester = priceless

True....but think of it like this....

It will be the cheapest modification for Mo Power that Ulysees has ever had to do :buttrock
