Awesome Jason, I can't believe what it's putting down through your drivetrain! <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> My finals are next week then I am out. Like you said, time to start racing again. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> I'll make sure to carry my video camera around with me and get some more clips of your car. Just let me know when you are ready to go back to the track. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

Just for an interesting comparison, I was wondering how the area under the curve compared to Jason's and Patrick's cars.

Here's a link to a photoshop version I did combining their top dynos together.

Heads/cam vs. just cam

Jason's is the blue and Patrick's is the redish color.

When Jason adds heads he will probably only pick up 25rwhp or so. I've seen it many times. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> [/QB][/QUOTE]

I think not. The last car that we added OUR heads picked up over twice that, without the CA correction added.

More like luck of the draw.. It seems that if we look at all the tuners the avg is 410 to 420rwhp.. Not having an exhaust would give higher #'s. We can go back and forth with who has the best setup, but there is no way you can compare dyno #'s from different locations at different times of the day. I can dyno my car at one place and end up getting 10rwhp more at another place using the same type of dyno just because of altitude and temp. Jasons #'s are awesome. Not just because of the cam, but because he is getting these #'s thru a 12 bolt and 4.30's with stock heads. Granite ls1edit helps, but Thunder Racing seems to have that down pack so far. I will be taking the trip up to Thunder myself when my car is finished to get ls1edit done.. Keep the cam swapping coming Jason..

Mike, the best comparison between Justin's car and mine was when I dynoed on Saturday. He previously did 400rwhp w/ the stock rearend/gears, aluminum flywheel, and carbon fiber driveshaft. After we changed his clutch, installed a stock flywheel and his Moser 12-bolt w/ 4:30s, we rebaselined his car. It did around 382rwhp/380tq, very similar to Chris's car.

The only difference between my car and his on Saturday was I was running 4:10s compared to his 4:10s and I had a 3" ORP compared to his 2.5" FLP. Other than the cam differences, that was about it. This was when my car did 401rwhp.

As I posted above, I'm using a stock flywheel (resurfaced.. saved less than 0.5lbs <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" /> ). The tire pressure was not changed between any of the dyno runs and it is exactly how I drive it on the street.

I'll try and make it out to NPR in a few weeks. Once school gets out, it will make it alot easier to go race on weekdays. I can't wait to get back racing again.

Terry, I never said the car was going to dyno 460rwhp+ after heads. If it does 440rwhp, I would be more than happy. I know this will be more than enough to run 10s w/ a hydraulic cam. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> I just need to get the car to 60'. <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" /> You asked for how much the car Paul was talking about put out cam only. This just shows the gains are possible.

Think the optimal camshaft profile will change once the heads get ported.

I also think the larger tube headers are only going to shift the rpm at which they start working for you later in the powerband, possibly
too late.

Think 1 3/4" are optimal for the powerband and rpm levels these motors work at.

I think that with a good ported set of heads
that a good 30-40rwhp will be rewarded. 60rwhp would be very nice, not sure if its going to happen.

Keep the headers you have,they are working for you, probably really starting to scavenge hard so the exhaust valve doesn't need to hang open for ever.

SOmeone needs to make an intake for these that has about 20%-30% more runner cross section, and 2" less runner length - or heck tuneable lengths for that fact.

This would boost tq peaks on the big strokers and cars that want to turn rpm. Tq won't fall off so fast after the peak so good top end power will be made.

Sounds good Mike! I'll try and make it out there Wed, May 22nd. School will be out and its time to start some racing again. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Just to throw out some more numbers for comparison sakes. I switched over to a 12 bolt with 4.10s added iron clutch and steel flywheel and lost over 15rwhp from my 398rwhp dyno while still with stock heads. Now Chris98SS dynoed even more then me with stock heads. 402rwhp with Thunder 224 cam, stock rear/gears/FW/DS through the borla and bullet muffler. He added a 12bolt with 4.10s and dynoed 383rwhp no other changes. But I should mention both of our cars ran FASTER with less power. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> Does that make it a little easier, I think so.

Moral of the story, Jason's car is putting out the numbers through a stout drivetrain! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> If someone is just looking for a dyno number then throw in a stock rear/gears and watch the numbers shoot up 15-20rwhp. But thats not what it's about. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> Also, some cars are stronger then others from the factory. Paul, your old motor is doing Jason quite well. <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" /> <img border="0" alt="[chug]" title="" src="graemlins/gr_chug.gif" />

I think running open headers is OK, if it's the way you are going to race the car. Hell I usually drive around with an open y-pipe anyway. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> I see comparing dyno numbers with different setups is like comparing track times of cars that are different weights ( hardtop, stripped interior, no power options etc) and 60'.

Jason, you got me thinking about this cam for when I do a forged shortblock. Only thing is, it's not ideal for nitrous is it? I like the idea of making more power at the same peak rpm, but the increased cylinder pressure would make it more prone to detonate?

EDIT: should of read page 3 before I responded. <img border="0" alt="[boring]" title="" src="graemlins/gr_zzz.gif" /> DOH

Default Re: New dyno results! 410rwhp/389rwtq - stock heads!

Terry, Paul is talking about Chris98SS's car. He was running stock heads w/ a TR224/224 112lsa cam. We baselined his car before adding the heads: 383rwhp/381rwtq

The only thing changed was adding a set of GTP stage 2 truck heads (w/ a little tuning.. worth only 3-4hp since the car was pretty well dialed in): 443rwhp/421rwtq

Here is the dyno graph:
Addition of GTP stg 2 truck heads

Here is the thread:
GTP stage 2 heads/Thunder 224/224 112lsa cam

This was all through a Moser 12bolt w/ 4:10s, stock 17" SS wheels, stock driveshaft, and stock flywheel. This was even through a catback. I wonder how much he would have picked up w/ open headers.

Default Re: New dyno results! 410rwhp/389rwtq - stock heads!

Nice results!

But, in comparing curves and other dynos we should make sure to realize ALL the differences between cars, exhaust set ups, transmissions, compression, cams, and heads.

There is no denying these awesome results, but we should not deny the differences between what's being dyno'd. Jason's 4.30's arent dyno friendly in the least, which says alot for the setup, but its also being dyno'd with no exhaust, and I'm not sure what that says.

I'm sitting here thinking of Jsears' dyno of over 400 rwhp with the 224 cam. But, he had how ever much tire pressure(50 psi?), 3.42's, light-wieght fly wheel, A y-pipe and borla, and I think a Carbon Fiber Driveshaft. Is there any way I can rightly compare this to Jason's tire pressure, 4.30's, resurfaced flywheel (?), aluminum driveshaft, and no exhaust?

I'm just not sure how to understand these dyno results.

The car is making power, undeniably, and it is nice to see new things being tried every week-- good job guys.

I cant wait to see how your car runs Jason.
With 4.56 gears and open headers it should be nasty!

Congrats Jason! The people at TR have really done there research and should be commended for there hard work! This is a serious breakthrough and there customers are the direct benifactors. I cut this statement out from above.

"Get your car LS1EDIT'd and see where you stand, the results might surprise you. YOu might gain very little from porting except shifting the curves over to the right and dropping lower speed tq/hp a small amount.

If you stand @ 420rwhp/400rwtq with LS1EDIT you stand very little to gain."

I semi agree with this statement, I feel that a step down on the cam and a step up with the heads would yeild more quality and overall power. I would like to see those results myself. Great results never the less, keep up the good work!

Yes it is Justin.

Paul, I really want this cam. How would it idle, I have LS1Edit I can tune with, if I set it to the proper idle? I want this for my C5 and don't want the car to shake and vibrate my hand off of the shifter. Thanks man.
