I don't have a stock hood and have issues. My cowl air cleaner is setup for a torker 2 with a one inch spacer and works great. When I go up in height I use an air pan setup with a small filter for the street and no filter for the track..Always a battle with these cars..Years ago when I had a stock hood I was determined to run a shaker with a one inch spacer on a Torker 2 ,I stared at the car for an hour wondering how? The top of the carb was even with the top of the firewall! Once I got it figured out it was worth 2 tenths and 2 mph.

I believe you have the same hood a buddy ran on his TA some thirty years ago. He referred to it as "Turbo Hood". I figured out a way to fit a T2, two stages of nitrous with a 1" spacer and now an additional 1/4 in spacer. I always liked the "stock" look with this car. The picture shows the scoop a bit low... Before the addition of that 1/4 spacer

I lost two tenths and two mph on the red car going with the "stock" looking hood. Before that I used a factory Formula hood with a molded in forward facing Pro Stock style scoop.. Just the opposite of your gains.

Keep up the good work!

A tid bit for interest, and related in post # 81 by ta man and his comment:

"When I go up in height I use an air pan setup with a small filter for the street and no filter for the track"

I have a factory shaker hood scoop molded onto my fiberglass hood.
My air cleaner assembly goes up inside the hood scoop with the Victor intake.
It's a small K&N 9-inch diameter filter with X-stream filter top.
After the last cam shaft change we put the car on a chassis dyno. While at the dyno shop for interest I wanted to know the horsepower loss with the filter.
With the filter it was 591 HP at 6000 rpm to the rear wheels. Removing the filter it was 608 hp at the same 6000 rpm.
This with the current direct port fuel injection set up.

I have a 1/4x3/8 spacer on my TA with a shaker base and scoop-mainly to level the Shaker . it does pick up 0.2 without a filter in the base-first time I did it was a night TNT and lean popped out he scoop in the dark when i did a dry hop when the mixture was tuned for the filter! Flowed good enough to run 124 weighing 3750 .

With limited information on your dyno sheet and some guessing it looks like an 1150 was a good choice.

Brian,
Gach has not replied to my post. I used information from a dyno sheet that he posted sometime ago. I am guessing that it is the dyno test he is talking about above. Gach can post the dyno sheet if he wants. This is what is on the dyno sheet.

TA MAN, when does the track open for you? Just wondering how long we will need to wait for this testing

St Thomas opens May 11, Toronto Motorsports park hasn't released their schedule, but it may be earlier.
I'm tempted to swap intakes at the track especially if its at TMP..I can usually get more runs in and the track is better and the pit area is better.
I'm excited to get out this year,last year was the first not doing any track testing. I know even without swapping intakes the car has a 10.60 or quicker in it in decent weather. The car has 60 footed half a tenth quicker than my best et in my signature. I would like to see some 10.5's this year and 128's for mph but I need the track time..car doesnt get quicker sitting or myself sitting at the laptop lol, I need to feel the frustration and joy of the dragstrip!

[ta man]

It will most likely be mid summer before the intake swap test at the dragstrip. I just installed Wilwood Dynalite Pro Series front brakes which dropped 12 lbs off the rotor/hub assembly on each side. I'm also switching from a clutch fan to a dual Derale setup with a new aluminum rad. It will be interesting to see if the car picks up a little with less rotating mass and electric fans.

Keep us posted and ket us know how the electric fans cool compared to the clutch fan

Yes for sure..it was a tough decision to go away from a clutch fan and my trusty rad. The shroud does have the air flaps and the fans are rated at 4000cfm, I'm also using a Delta Control PWM .
