All you need is a compression guage and a lot of time.. What you do is you take a sparkplug out, stick the guage into the sparkplug socket and start the engine.. You should do this 3 times to every cylinder and take the most consistant one.. For some reason though, it never takes as long when i'm doin this to the geo where as if i'm doin it to the stang or something... weird
Originally posted by Fallguy That's good to know. Nice number's . I'm glad they held for you. Your car has all forged internal , correct ? I wonder if the 2v would hold up just as good ?
I got my 3.73's in the mail today. I hope I'll like them . They just sounded like a perfect gear for me, but time will tell. I know live and learn,but in a prev. post you called us ignorant for getting 3.73's.If I don't like the 3.73's I'll swap to 4.10's or If I decide not to go S/C next year then I might. The gear's and swap are pretty cheap so I'm not worried about it.
I can only imagine how your car pull's with 4.30's . It must be a blast !!
One more thing that scared me away was people alway's talking about traction issue's with 4.10's. I plan on keeping my stock size rim's & tire's , so what would happen with the 4.10's ? Would I just spin all the time ?
Clue me in guy's

Forged Internals? No, my engine internally, is COMPLETELY stock. Stock heads, stock cams, stock intake, stock pistons, stock rods... I've only done bolt-on mods.
Traction issue... easily resolved by getting some maximum motorsports lower control arms, subframe connectors, and some good Kumho Ecsta MX / Nitto 555R's
Yeah i wouldnt really call that a good test...thats not nearly enough miles, and with out another car with differnt gears that was driven under the same conditions.. this test really dosent prove anything other than your car still has compression

I was thinking the same thing, but I just didn't say anything.
The only reason I brought up the engine wearing in the other thread was because naturally when you run something at a higher rpm it will generate more heat & wear. That's kind of Engine 101... Just like with NOS although it's a power adder & a damn good one it also washes your engine clean when ever you do a shot. (not technically speaking) but you get the idea. It will shorten your engine life . Especially the bottom end.
As far as internal's go Milw. the reason I asked was that I know Cobra's have forged internal's from the factory. I honestly don't know about 96's though... That's why I asked.

the only forged internal in the stock cobra engine is the crank.
57k stock gear miles and 15k 4.30 gear miles, while it might not be a ton with the new gears, the numbers are still WAY up there.... and thats REALLY the point here.
in my ever growing pursuit of proving all you 4.10+ gear naysayers wrong

Sorry, I was confused about the point of the thread...I guess I thought it was to prove some boys wrong. Which one of you said his compression numbers were going to be bad?
