Corvette C5 w/ vara-ram vs Evo 8 intake exhaust

[VenomInMyVeins]

Whadya think? Automatic corvette c5 w/ vara-ram dual ramair to 1 cone.. vs manual evo 8 with basic catback and k&n filter.

It's gotta be close cuz stock both cars get approx 0-60 in 4.9... but the evo will top out quicker cuz it's a turbocharged 300hp 4cylinder w/ awd... but how would it do in the 1/4 vs a 390hp c5?

Plz no newbs reply.. it'll piss me off to hear "C5! it has 90 more horsepower"

it also has only 2 wheels to put the power to the ground vs the evo's 4... but it has wider stickier tires stock.. but it's heavier.. but it's an auto and the evo's a stick.. but the auto has a tourque converter... so there are a lot of tradeoffs and I want some pro opinions cuz I'm puttin money on this race...

Oh.. btw.. my vette has traction control too, so I won't burn any rubber off of the line, but I'm afraid it might control it so well that it'll drop the power to the tires down too far. Yeah.. HELP!

$$ on the line

all auto's have torque converters and why would that be an advantage?At least that how your post made it sound.


BTW those cars need to have more than the mods you listed to put out that kind of power.

Anyway if the power numbers you posted are correct the win should go to the C5 90 hp difference should more than make up for the weight difference

but you also got a torque convertor to absorb all that power so it doens't have get to the ground. and evo takes mods extremely well. a standard C5 5 speed runs a mid 13 to low 13 in the 1/4 mile. a auto will not be as quick. a stock evo 8 runs a mid 13. with the bolt ons, it would be near a low 13 to high 12 second car.

"the torque converter actually gives your car more torque when you accelerate out of a stop." - http://auto.howstuffworks.com/torque-converter3.htm

Okay thank you neutrino for answering exactly how I didn't want you to. A torque converter puts the power to the ground with more torque because you don't have to worry about as much power being lost in the mechanics of a clutch. The evo is a stick. The vette is an auto. And 90hp is not enough to be able to beat an evo.. you have to look at more... such as the gearing and the drivetrain. A vette tops out at over 180mph.. an evo can't touch that. So there is more power in the vette but it's put towards the higher end.

So now that we've had that... TatII The evo doesn't even have a racing chip... so I'm guessing both cars are going to be in the low 13's because the vette has a vara ram system (most of u probably don't own vettes so I will divulge you) You all probably have seen the 2 holes on the corvettes front facia. They do nothing but house the fog lamps. So what vararam does is remove the plastic fillers and replace them with two air ducts that go into an airbox that is larger than the stock one and goes to 1 k&n cone. So the vette has 40 exta horses than normal according to the factory, and according to the factory it's supposed to get .35 better in the 1/4 mile. So it's close...

Little misinformed arent we? the torque converter puts down more torque at launch due to torque multiplication, that's the advantage they have off the line, which is why you see many drag cars running automatics. There's more parasitic loss involved in a converter because it's a fluid drive, and even when its mechanically locked you've got alot of fluid spinning very fast inside it.

The evo8 is below 3300 lbs? if it is, it isn't by much, and it's AWD drivetrain will eat much more of its power then the corvettes RWD, and while the evo may take the launch it'll be blown by in a matter of seconds. 90 BHP is more then enough to take a car that only does as well as it does in the 1/4 mile due to its AWD drivetrain, the evos trap in the 102 range where the corvette is doing 109's, right there it proves there's much more acceleration in the corvette, the wheels just cant grip well enough to do it.

The corvette is geared to do over 200 MPH, the reason isn't ot DO 200 MPH+, its because 6th gear is wide for better fuel mileage. the 1st through 5th gears are plenty to race with, 6th is too wide for even the Z06 to pull in, and the viper with a similar ratio can only huff up to the 180 range before running out of steam in 6th.

C5's have run high 12's just as the Fbodies have, with the intake chosen and a good driver it will be a high 12 car if driven right, the evo8 has a chance of course, there isn't a massive idfference, but if both are driven to their potential it'll lose.

Uh, the vipers top speed is like 185- 192in 5th gear. The new 500HP one, like 183(more drag.. .35 vs .40+). So if you're gonna tell me the viper is gonna top out at 180 in 6th gear, I'm just gonna laugh at you, because it would be more like 150-160, maybe. .50 is a huge gear, so is the 3.07 diff.

the Z06 has more then enough power to maintain speed in 6th gear at around 170 MPH, the viper has another 100 ft lb on top of that. The gear difference isn't massive, considering its extra torque if you dont think the viper can maintain or even accelerate in 6th I wouldnt even waste my time laughing at you.

trust me i know how a torque converter works. i got to school for this stuff, also like what FYRHWK1 said, it takes more time for the fluid to lock both parts of the torque converter. plus the even at full lock there is still power being lost. a stock auto can not out launch a stock manuel since the stall speed for a stock car is just too low. also autos from the factory doesn't shift as fast, but since you said it has a chip in it, it should help the shifting, but considering that most autos have only 4 speeds, i'm not sure if the vette has a 5 speed auto though. since it has one less gear, that means the gear ratios are spaced further apart, which actually hurts aceleration. also a clutch will have a solid transfer of power with lose since its pretty close to being one intergrated part. how many stock auto vettes can chirp shifting to second? the evo stock can chirp all 4 wheels shifting from 1st to second. how is that a disadvantage? the numbers that you guys posted are from a 5 speed C5 driven by a pro. but yoru comparing a vette with a chip and a intake, with a stock torque converter. you guys also underestimate the power of the evo. you give it a chip, a full exhuast, intake the thing gains about 100 whp. which makes it put down over 350hp and will run mid 12's all day long ( well as long as the clutch last ) the evo is tuned extremely rich from the factory. you can lean the shit out of it and still be running rich.

[Neutrino]

thanks guys for explaining to him that having a torque converter its not an advantage due to its parasitic power loss....the only advantage he would have with an auto is more consistent runs....


and that ram air system you mentioned vemon i'm sorry to anounce you that will not give you 40hp....you are using advertised power gains what we also call ricer math to calculate the 390 hp...the C5 has already a good induction system and those ram air systems (beside bringing in cold air) dont do much else and slighty colder air will not account for 40 hp even in a 5.7 liter engine

and i also doubt that the evo has 300 hp out of a k&n and a cat back...true a high flow cat back will help but 29 hp NO....i've seen plenty of dyno sheets to confirm what i'm saying.....as TAT II said the best way to get power out of an EVO is to reprogram its ecu and make it run leaner....but the evo you mentioned was not chiped

so sorry if I offended you with my reply but do please bring some more reliable info to the table...dyno'ing your car would be a start

I have never seen a test, but I highly doubt your infomation.
If the top speed of a C5 Vette is reported at 175mph, and then you go to 6th gear(.50, 5th gear is .74), your not gonna just drop 5mph I'd say they'd drop to like 160.. But I'm not certain, but it would def slow down. Vipers also have worse aero too... they have 100(now 150) extra horses, and they only go about 10-15 mph faster.

And I highly doubt your information, since I've driven a Z06 and felt how it pulls in 6th I'm well aware that it cant accelerate in 6th above 150, it can however hold speed fairly well. you'd say they'd drop to 160? well i'm overwhelmed by your proof, considering its you're own guess i'm just gonna drop this.

Vipers do have more drag, but 150 extra ft lb is 150 extra ft lb, and the aerodynamics have gotten better with the SRT-10 (yes even witht he scoop) and ts done over 180 MPH, numbers that cant be reached in 5th because of a lack of redline.

[Altimas]

Dude you have no idea what your talking about. An srt-10 has .40 drag with the top up, and .43 with the top down. A 2002 viper has .35
And a viper can do 213 mph in 5th gear, at 6000 rpm. It has a .74 5th gear, and 19" wheels on the rear end
So go ahead and take your"facts" and stuff em.
Oh and yes I say 160, maybe 165, cuz the top speed of the vette is quoted at 175mph are various places, I think the z06 can do like 180 mph.
EDit- and whats this BS about no redline? It has a 6000 rpm redline, not sure at what point the fuel shutoff is at, but the 2002 was at 6250

#1, you have your numbers reversed, if you cant even get the years right then you're lost. Whether you say 160 or 165 doesnt matter, I really dont care considering the source. As to the redline, i never said "no redline", i said it will run out of redline in 5th gear, and i was referring to the corvette.

[Altimas]

Ya I noticed that(numbers reversed) but didn't wanna change em(was like that on the site I got the numbers from.)
Also, I kinda though you were referring the vette, but your poor organization of thoughts prevented me from knowing for sure(You were talking about the viper, then out of no where you meantion running out of redline.)
Done with thead.

you get specific numbers completely backwards, and then try to talk to me about poor organization of thought
