Ahh yes.... Mobile phones and endless meetings have proven an excellent business resource for Manny.... :D

My pleasure. I'll try not to stick my foot in my mouth too much on your behalf :)

Your doing fine so far, keep it up

Actually one question I couldn't answer but I'm sure might come up... Is that local pricing or shipped?

That is shipped to any location in Canada :canada:

Thanks guys! Thinking that was a little cheap for an Intake manifold, not too much to gain from a cold air kit is there? I put them on all my cars and didnt really gain much if anything on the dyno! Now a good intake manifold would give me a little? So what price can I expect tp pay for an intake manifold? And is there anything available used?

The Vararam will give at least a 38 RWHP increase in performance , just ask anyone that has one. A true cold air intake will not show up on the dyno as they only work at speed , say around 25km and up . The Vararam is the best there is.
I tell you what , you buy it and have installed here and if you do not notice the increase in power right away,I will refund you entire purchase. An intake like an LS6 will only give you around 10-15 RWHP and cost around $400.

Let me know :D

The car already has longtubes,high flow cats. Not sure if the car was ever tuned after the exhaust work,so I will want to get it tuned with or without any additional work. Wondering,when you say tune do you mean on a dyno?
 
dyno is preferrable but I also have a Diablo programmer that I'm actually going to be selling. Good thing about it is that you can actually make some really simple changes and also diagnose DIC codes. A full dyno tune can run $600 or so but can yeild better results but that also depends on your tuner. If the 1-4 skipshift has been disabled then someone has been in there at least for that :)

If it was not tuned you would be throwing codes, not to mention it would not pass the Ontario E-test . So I'm pretty sure it has been tuned. The Vararam can be installed without tuning, however your vette will perform better if it is tuned. It is something we can certainly look at. By the way our dyno tunes are only $400.00.

That is a very good price for a tune Manny. Our local tuner charges $600 (which I always thought was fine) and other shops have quoted me $325 just to hook up their computer without any guarantee that they can make any changes as they have not tuned a Corvette before!
 
I usually pay 100 per/hr,and seldome did it ever run past 2hrs. But that was a mustang.
 
Just ordered the Vararam Intake from Manny! Looking forward to the install and to feel the gains! Thanks Manny!

Thanks! But I have been throwing money at cars for years. Do not think I will be going crazy with this one,all my past rides have been way to expensive for the amount of use I got out of my investments. After reading,and all the advise I have got from this club(thanks) I thought 30 to 40 HP gain was reasonable for 300,and virtually unachievable with past projects,I have had to spend WAY more in the past for results such as these. Oh and it looks pretty cool as well!

30-40??? Prolly a little on the high side!!! But agreat upgrade regardless!!!

Actually 38 RWHP to be exact:

Right from the Vararam site :

The VR-B2 features up to 40 HP throughout the RPM range
Specially designed water trough system helps dissipate any incoming water
Increases throttle response
Increases gas mileage 1-3 MPG
Increases acceleration
No cutting or drilling
Comes with VR Super Street filter
OEM Look and you get to keep your fog lights!

All ram air boxes are about the same aren't they?

We love answering this because in the after market it seems that very few ever care to really talk about or emphasize to you the customer that if you want a fast car you need power and torque developed under the curve. Everyone is so concerned about peak power on a dyno that they forget two things: 1. The car needs power under the curve to accelerate. 2. The intake system must be able to recover, build and maintain air pressure as quickly as possible. This means making the intake as efficient as possible NOT at PEAK but during shift recovery under the curve requiring proper air box design and internal systems to increase velocity pressures to help offset any head loss incurred in the system. As independently dyno tested by Cartek and C5 Super Tuner shootout winner Danny Pop, the VR-B2 made anywhere from 2-4 rear wheel Hp more than this competitor at peak but at 5000 Rpm they both saw 5-10 Hp more while sitting on a dyno on stock and modified cars. The VR-1B was designed to perform under the curve. The system will typically gain the same or more torque than Hp depending on the filter used and the year of the car. Take a look:

(the test car is a 98 A4 with 2.73 axle, other than these intakes, car is stock) Initially the VR is already maintaining +.25 Psi more at this recovery point, in 1.5 seconds the VR is +.34 Psi from its competitor. Now let's talk about Hp differences using the same Hp/Psi formulas as mentioned elsewhere on this page.

This car pulled 299 Hp at -.89 Psi with the competitor and 302 Hp at -.89 Psi with the VR (this car averaged +2-5 Hp under the curve with the VR depending on the Rpm). This will yield 21.657 Hp/Psi and a 21.874 Hp/Psi respectively. At shift recovery that equates to 303.19 Hp, the VR produced 311.70 Hp. That's a 8.5 Hp difference at just shift recovery from pressure alone, not including any difference on the dyno we will use the lower numbers (2-5 Hp @ 5000 Rpm). That's a 10.5-13.5 Hp difference. 1.5 seconds later there is a +.34 Psi difference, 14.21 = 307.75 Hp vs. 14.55 = 318.27 Hp. Now we are looking at a 10.52 Hp difference from pressure only. Once again you add the dyno difference using the lower number at 5000 Rpm (+2-5 Hp) and you have a 12.52-15.52 Hp difference and we are only at about 80 Mph. Now peak Rpm, the last second before 90 Mph. 14.54 = 314.89 Hp vs. 14.74 = 322.36 Hp and now add the dyno difference at peak (+2-4 Hp) 322.36 Hp +2 Hp = 324.36 or a difference of 9.47 Hp. The only problem here is that as speed rose (not shown on the chart) to a typical C5 trap speed the competitor lost -.14 psi (caused by air spillage pointed out elsewhere in this discussion) bringing the VR back to the full +15 Hp over travelling through the ? mile traps. If multiplied by a 15% correction factor for an automatic car that would be a +17.25 Hp difference travelling through the ? mile (remember the Mph difference of 1.7 Mph).

If you had to put an percentage to it 60-70% of the time in gear a VR is 12-15 Hp stronger and the last 30% its 12-9.2 Hp stronger than its competitors. This is the current area of racing engine development that is being concentrated on. In the old days you used a dyno. These days it's used for general measurement and to run engines in before being installed in the cars. If someone has designed a ram air system on a dyno then it has a 90% chance of not working well at normal road speeds. It will simply take too long to pressurize or the ducts will be to short and air spillage will occur and the pressurization will be nil and all that you will have is a filter hanging in the wind.

A proper ram air system is a very complex item to make function properly at road speeds below 100 Mph. We spent over 2 years developing the Corvette C5 unit but our parameters were for OEM, not all-out race use. Our competition makes around 28-32 Hp through a 1/4 mile. The VR on a standard C5 or Z06 averages 35-43 Hp through that same 1/4 mile but the VR will make power and torque faster enabling it to be much quicker even on a dyno. "We picked up 5 more Hp at peak over the Donaldson on our basic 390 rear wheel Hp car on or chassis dyno. " Cartek Racing in Garwood, NJ using a VR set up for their cars (1 inch spacer in front of the filter vs. standard 1/2 inch), they were seeing 2-4 Hp more at peak Rpm with a VR-B2 but at 5000 Rpm they were seeing as much as 10 Hp more with the VR unit. Here in lies one of the many reasons why the VR is so quick. The system was designed to be adjustable by simply increasing or decreasing the plenum volume to suit a given cars power needs static. This feature combined with the low pressure drop across of our competition air filters allows the system to make more power under the curve and with a very efficient internal duct package it will force feed more air at lower speeds making for a much quicker and faster car.
