Well true i half to agree but depending on what ur goal on power level is at the end.. for a few hundo more u can go with a monster that can handle much more hp.. so i agree but then the 10 bolt will go! Never ending battle lol but for me just being a cam only at 400 hp it works just fine tho. Ls7 clutch i was told can handle like 550 crank hp or so..

 

With your cam, why wouldn't you spin it higher? I would think that with that cam your motor would continue to make power higher than 6400.

 

Kudos to nick for getting the win light 2 times. However as expected 5.bro is much faster overall ET and trap. Fun day.

 

Something light....Lol monsters, normal specs, ls7 etc are all heavy SOB's which is a lot of parasitic loss where you dont need it. I run a mcleod rst with a fidanza fly and my setup is right around 32-33lbs and was a huge improvement over stock, and still drive close to it. I just posted up some vids for people in the manual trans section of me dding it so check them out and dont listen to the people who say its too light to DD.

Hio runs some witchcraft tilton unit that weighs like 17lbs and hammer runs a spec mini iirc. The mini twin is nice but was a little out of my price range and wasnt much less weight it comes in about 24-25lbs iirc with the fly.
See above, get a light clutch its like free hp since you need a new clutch anyway. And an ls7 might hold that in a 3000 lb vette but its a real stretch in an fbody plus try shifting an ls7 at high rpm and hot lapping it at the track...doesnt work well

Nick raise that shift point at least shift it around 65-6600 your sacrificing some mph there at the strip. That cam probably peaks right around 6100-6200 and doesnt nose over for a while. Turn it harder

 

I plan on raising it. That's just the way it is with my current tune I guess

 

Spec xtrim is a good one. Quarter master has very good clutches......maybe even the best clutches. You want something much lighter than what stock is.

This clutch i have no experience with but could be a more cost effective alternative.

Do you have a dyno graph you could post? I would think any aftermarket cam/springs worth it's salt should spin to atleast 6800.


It's not about the hp it can handle. ....it's about the weight. Monsters are to heavy to. The car nick raced has a 40bl clutch and fly in it. No reason for any ls car to have a 50+lb clutch/fly. The ls7 **** is over 60lb.
For sure.

 

fun for you! blower bully going 100+mph in the 1/8

 

This was the first pull on the dyno. Only picutre I have. Dyno sheet is with my brother, who lives about an hour away. Took 3 more runs on it to get 370 out of it

 

Good info about some clutch's lol. i know the weight on ur clutch's mattered but i have read somwhere on ls1tech that there is a sweet spot in the lbs? Too light it has a big risk in bogging and to heave it robs hp??

 

This is a V8, not an inline-4. There is plenty of rotational mass and torque due to the large crankshaft and 8 pistons. Only thing I would worry about with a light clutch is the durability.
And I sure as hell wouldn't buy a heavier than stock clutch, certainly not with the minimal mods here.

 

Should be spinning it higher. But the ls1 intake will be choking it too

 

I agree completely

 

True with flywheels also. Light weight aluminum flywheels removes rotating mass from the drive-train since it stores less energy. Because the lighter flywheel stores less energy, it works well in situations such as roll racing. On the other hand, since it stores less, it also returns less which does not work well in a situation such as launching your car at the track.
You have to almost decide what you want to do with your car and then buy the appropriates parts to help with that.

 

Also hard to get a good trap speed when you shift lol

 

Is the LS1 intake that restrictive that you could not make more power by increasing the rpms? It may not be efficient with respect to making the "most" power but it should still help out I would think.

 

Specs for his cam are,
224/224 .581/.581 114LSA
There is an optional 112LSA too, don't know what he has.

 

Lol, wut. This might apply for an i4 or for a 6lb clutch, but not here.

 

I think nick has his next round of mods picked

1. Clutch/FW
2.LS6 intake
3. Gears

 

The energy stored in a flywheel not only smooths cylinder pulses but also helps to accelerate the car. It does this by storing and releasing energy. A lighter flywheel removes rotating mass from the drive-train but since it does not store the same amount of energy as the heavier stock flywheel, it does not give as much energy back to help accelerate the car. Read up on lever (moment) arm as applied to torque. It is not related to i4, v6 or v8. It is physics which applies to all things

 

Are you saying it will actually raise ET? Interesting...
