    Cool Just put the V on the Dyno

    Hey guy, I've been lurking through the board for awhile now but I never posted. This is a great board! Anyways, I took the V to Speed Inc. last night to get a baseline dyno run. It pulled 321.1rwhp on the second run. Then they added their new intake system and my horsepower jumped up to 335.8rwhp! I am extremely pleased with the system. I'll post my dyno sheet and a couple of pics a little later.

    I think that it cost $179.00. 14.7rwhp increase for the money is awesome. They did a great job and were very professional. I can't wait to get more stuff done to the car.

    Their intake is one that they made for the GTO. They had one customer who had a V and asked if he could try it out. They sent it to him, but he told them that it didn't fit. My car was the first V that they actually had at their shop, and it only took the about 10 min. to get it put on. Overall I am very pleased with the look and performance of it. They don't usually post on this board, but the do post alot on ls1tech.

    Great! Can you show us pics? Did they have to modify the GTO kit to fit in the V?

    Yes I can see that (had seen the pic before). I was more interested in the smooth tube from the filter to the Throttle Body - does this fit into the V without any modification? You couldn't pay me to put a K&N on my car - I'd have swapped the filter off for something else.

    Is there any wall to keep the hot air from the engine from getting sucked into the filter?

    Is there evidence that a wall reduces intake temps?

    My friend has a cold air intake on his 1995 M3, and has the sealed wall (looks very similar to More Performance's).

    I asked him this same question a few weeks ago when I was debating on whether or not to buy More's CAIK. He whipped out his laser themometer thingy and with the car running at temp, he popped the hood and did temp readings on each side of the wall. I don't remember exactly what the temps were but I think there was a difference of like 25-30 degrees (I think). So there was a somewhat substantial difference in temps; big enough to change HP-I don't know).

    I can see that.

    Just as an FYI for every +/-7 degF in temp change is +/-1 HP or thereabouts.

    But that test actually showed very little, because you weren't moving! I've done similar tests with a probe stapped to the air filter (hood closed during normal vehicle operation) under normal driving conditions, with a walled CAIK then with the box removed - once in motion there wasn't much difference. In some cases the air flowed better bc there wasn't a box to restrain the intake (but that really depends on where the air comes from and where it can go to in an engine bay). I'm going to try to get the air from farther DOWN in the engine bay and see if that does anything.

    I just don't see the huge impact of the box (esp a metal walled one where the metal can get warm, now an ABS or CF one I would try) - but to each their own.

    Actually, should be closer to 1% HP for every 10degF temperature... 4 HP...
