yes you are correct. if only i was as 'smart' as you.

glad to see we can both be smartasses


im just tired of seeing companies advertise "totally streetable" packages.............pretty much every damn mod you can do is "streetable".

glad to see we can take humour lightly.

i was talking with the crane rep while he was there. they aren't trying for a drag strip bruiser. the most flogging this car will see he said was on the dyno. they are thinking of putting 18" or 19" wheels on it. it is an attempt at attracting the younger crowd.

266 rwhp stock? That sucks.

compared to your v6 it's great. but anyways, 266 divided by .85 (15% drivetrain loss) = 312 hp
so it's not far off.

still, thats really bad stock............i mean, the fwhp should be 320 stock, not 310ish.........and most ls1's make more than rated. this one just looks like a weak car.

agreed there. i had a 94 z28 and a 94 formy at the same time. identical motor, auto, and 2.73 gears. the z28 went 13.98 the formy went 14.40. the formy have 20k less miles on it. talked with vinci. they said deck heights on the motors varied so much it was pathetic.

What the hell are you talking about? Who said anything about my V6? Grow up. We're talking about an LS1 here. 266 rwhp is the lowest dyno # I have ever seen for one. It did respond very well to the VHP Stage2 treatment though.

calm down there skippy. i was poking at you. 266 doesn't suck compared to 160. it's all relative.

Remember, we're talking RWHP here, so it's ~130 to 266.:D

i used to own a 95 v6 manual before the 94s. ran 16.9 stock winter timen stock replacement filter, flowmaster dual outlet muffler, under drive pulleys, superchips design my chip ( got it free because they needed a guinea pig). dropped to 16.3 summer time.

but hey i was trying to boost you up there. you might have had mods.

Please remember that Vinci has a policy of dyno'ing all cars with the hood down. I'm not sure if they use fans. This does make a large difference in the results.

Most shops do it with the hood open - I think more or less so that they're on a level playing field with other national shops. However, Roger feels this isn't the correct way to do it. Just makes it hard to do direct comparisons.

first of all...........i seriously doubt that having the hood up makes much of a difference, except if you were doing many dyno runs in a row and the engine got too hot.


second.........running on the dyno without fans IS DUMB.

i would never goto a shop that ran dynos without fans.

when a car makes a WOT run on the street.......tons of air is forced across the engine, keeping it at proper operating temps.

when on the dyno, no fan is going to be able to duplicate the airflow of the real world, but not having a fan at all is just rediculous, especially here in florida, or on boosted cars.

first of all...having a hood makes plenty difference. on the ls1 cars the air enters under the lid. so with the hood closed it doesn't get as much air as if open.

second....they have a fan it's about 4 feet in diameter.

also they run the engine at operating temp. they showed the car temp at the 195 range. most other places run the engines cold or maybe at 160. big difference there in numbers.

does this math make it better for you

266 divided by .83 (17% loss) = 320 so to me it's a more accurate way of dynoing. so when dynoing with hoods open, engines cold, air lids open, you get false higher readings.

an n/a engine can only suck in a specific amount of air......i doubt that amount changes with the hood open or closed.


it would be interesting to do a back-to-back dyno testing to see if there is a difference.........im guessing less than 5.



as for having a fan, someone else said they did not.......i was just commenting on that.

yes an engine can only suck i nx amount of air. but if the underneath of the hood is too close to the inlet, it will restrict the amount of air going in. just like any air intake design. for the lt1 cars for instance. taking the stock ducting off and putting the k/n FIPK kit has shown up to 20 peak hp more. has nothing to do wit hhow much the engine can pull in. has more to do with intake tract restrictions not allowing the amount of air needed to get in. yes one day someone should do a back to back run. vinci said they have on the SS cars and it picked up. seeing as how the air enters the center of the hood makes a 180* turn to get to the front. then makes another 180* turn to get into the air lid.

as for the fan, just clearing up that they do have one. so no misinformation is out there.


pic of the inground dynojet with big blue fan:

and yes we are cheating that day with the hoods up. but the hoods on thirdgens don't cause any restriction. and no that's not me. here's mine. the governer broke i nmy tranny during the first run. so only had 1st gear. no n2o run yet. maybe in 2 weeks.

The only person who made a reference to a fan was me. I wrote:

Don't put words in my mouth. I've already seen the back-to-back dynos firsthand, but I can't find anything on the web for proof. I'd suggest you do a back-to-back test on an LS1 since you want to disprove the statement.

Here's one from a 1996 Ram-Air TA, best I can find so far:

Dyno hood open vs. closed (http://www.ws6.com/hood.htm)

and to think the pontiac ram air doesn't have all the turns a SS hood has.

i was thinking of CAI cars...........i can see how it makes a difference on ramair cars!

even still imagine the restriction a non ram air hood has if the ram air makes power over stock. but yes cold air kits for non ram air hoods make no difference.
