And on that, you have avoided many questions that we have asked you.
You would be surprised how many people care about mph. And 11.20s just shows you can drive the car to its full potential and also grab a good amount of traction.
A local Cobra runs a 2.3 whipple running 19lbs of boost. He put down 627 rwhp and 628 tq. His best at the track is a 11.4 @ 122mph. Car has a cage, solid axle 9" and gobs of other ****. Keep in mind our track is @ 2400' elevation and we dont see much better than 3000' DA. Here is a link to the car http://www.spokanespeed.net/forum/sh...14&postcount=1

11.2s also shows that you are way off in your "argument".
well nicely ask me some questions and i would be more then willing to answer them. I never said a car with a 3.4 whipple going 9.90 was faster then an eaton car going 9.90. But i would imagine that you, me, unit and any car enthusiast would rather spend less money to get there (assuming it wasnt less money to take short cuts)

Buddy ran mid 7s (would be mid-high 11s in 1/4) with 11#s and a bolt on cobra with nittos in 2500DA.. I'm sure with his new set up he can hit low 11s. I'm sure if it was more of a "drag car" (SRA, weight reducion, etc etc) he could go 10s. On a stock unported Eaton, in not so good DA.

Just go back and quote/answer our questions, I am curious to your answers.

Verdad Gallardo ok we will start with my mods.... My old setup( currently no motor in the car) was a forged 347ci ms4, 9.8:1cr, stock unported 241 heads, PP intake, ud pulley, 1 7/8s kooks, built 4l60e with 3500 converter, alumiunium ds, stock 3.46 gear.... and a solid amount of weight reduction. Never had this setup to the track due to a cracked windshield and failing tech. I built it all myself from the 70 ft lbs on the rod caps to the head bolts. Nothing was done by anyone else. The fastest et car i roll raced and beat was an 11.8 at 116. I pulled him about 1 1/2 to 2 car lengths. The fastest mph car i pulled from a roll was a car that went 12.2 at 118 mph. I beat that car by around 1/2 to a car. My buddies ported/pullied SRA, bolt on, tubular suspension cobra trapped 124mph and pulled me around 1 car to 1 1/2 cars.

Karls East Coast Speed does not have one eaton cobra in there line up.. They consist only of KB and Whipples. I dont know if you have ever heard of them but they are in the top 5 (cant remember exact position) fastest street driven gt500s
and as far as the money to how fast your car 1/4miles ratio, between an eaton and a whipple/ken bell. That is all determined by how fast you want the car to be. If your looking for high to mid 9's then yes a whipple/KB is the better choice financially. Yes you have to pay the extra money for the actual blower unit. But the extra size/ power/ efficiency you get from the blower makes it far easier to go down the track faster then with any ported eaton blower (not to mention heat soaking). The only 03/04 cobra in my area in the 9s has a ported 3.4 whipple on it. The fastest eaton cobra has run 11.3. Both have SRAs but the whipple has an auto and the eaton car has full front and rear tubular suspension. Not to mention the whipple car is far more consistant do to much less heat soak. Eaton Cobra hot laps into the 11's. Whipple cobra only drops a couple hundreths.

o and as far as suspension goes, the 9.90 whipple cobra has just front and rear adjustable shocks and the rest is full stock suspension. The 11.3 eaton car has all tubular, poly, adjustable this, adjustable that, etc etc into the suspension.

this is the only video my friend has of his 9.90 at 140mph 3.4 whipple cobra. Its a terrible video but it gives u an idea how fast that car is. Its just a simple speedo pull from 60-120.

another example of the money/1/4mile ratio. Lets say you had a dead stock f body. Your choices would be to run an n/a build or a procharger build. Either way your gonna go fast. Lets say a procharger kit costs 5k to completely bolt up including fuel system. Lets say a basic H/C car costs 4k with all necessary supporting mods to use the heads and cam. 9 times out of 10 the procharged version is going to be faster then the basic h/c (assuming the procharged car is running a decent amount of boost). Now knowing the procharged car makes more hp, it is going to cost you far far far more then 5k to build an n/a car that will out run that procharged car. I know this is a very rough analogy but its the same principle as the kb/whipple vs eaton. The less power your car makes, the more money you have to put else where into the car to make it out run a car with higher hp. Anyway. Im not trying to start an arguement or a who has the bigger e-dick battle. But it will always cost more money to go faster with less hp(assuming same car).
if you think 9.90 at 140mph in a full street car weighing 3900 lbs race weight is weak, then i dont even wanna know what you drive.

iv seen faster on a stock irs, full weight cobra. your buddy's junk dont impress me. i care more about how well the set up works than how much money is dumped into it. id be more impressed by a ported/pullied cobra going 10's full weight on an irs/6speed. your friends combo should go faster than it does thats why i think its weak.
did u even read a god damn thing i said buddy. BOTH WERE ROLL RACES. It was a supra that trapped 118 mph. And what do we know about supras. They are terrible 1/4 mile cars. The 11.8 car i pulled by more then i beat the supra, also lost to the supra. As far as the compression, it had valve reliefs in the pistons which is what lowered compression. I was in the process of getting a set of cylinder heads to run 12:1 cr. And i dont know about you, but i dont know of many cam only setup gtos that can outrun 118 mph cars. Considering i beat every other cam only f body in my area with a pig of a gto. I also raced a friends AFR 205/ cammed, bolt on GTO and was side by side. Now idk about you. But i would be pretty damn proud to have an NA setup car with unported 241s and 9.8cr run dead even with another na version running afr 205s and 11.0 cr. Before you open your mouth and try and tell me i dont know how to setup a car, you should actually read.
