MOTOR BUILD FOR BOOST HELP

[No_Traction_B]

OK guys its that time. Not sure how much longer my stock ls3 will hold out. Im at 700rwhp now with a d1sc at 9.5lb of boost. Id like to use my stock crank and keep the same bore and maybe lower the compression a tad. I dont want a stroker. This motor is for stricktly street application. I want forged rods and pistons obviously, i already have a comp cam. Id like to run more boost. Aiming right at 1000rwhp. Whats some ideas and options of good products on the market?

So you want 1000 rwhp for the street and without stroking the engine.:troll:

First thing is you are going to need a bigger blower than a D1 to reach a 1000rwhp. As far as your engine build, give us a call, I will go over some thing with you that is a must when building your LS Engine for boost. I will have pics up this week of a members engine we are building for 1000hp.

You say strictly street 1000HP and don't want to change your crank!?!?!? I don't think that you can get that much RWHP from your stock stroke, stock crank and if you can with more boost/cam/etc., would you trust your stock crank!?!? If I were you and was spending that much money on a motor I would for sure get a "better" crank to go along with everything else. Good luck and can't wait to see how it all works out!

I would also put in an aftermarket crank if you are already going to be inside the engine. That being said, I am going for broke (possibly quite literally) in a month or two on my stock crank. I am using the stock crank in the build in my sig. I am changing a couple of things and seeing how much more power I can make. I read a lot of builds making 1000 on the stock ls1 crank and living. LS1 and LS3 crank have same stroke.

What state are you in? Let us know if you need more info.

[Chris-HPS]

Guys, these LS Stock cranks can handle well over 1000hp. They can also handle 25-28psi boost without issue. Obviously if you can afford and/or want to stroke the engine, then sure buy a aftermarket crank, however the stock cranks will handle your hp goals all day and everyday!

Im in florida sc2150. Anyways. Yes ive read and my tuner agrees that the stock crank is great even over 1000hp.. i guess what im asking is, what pistons and rods should i go with for high boost. And what is the advantage or disadvantage of adding stroke.

Well if my d1 made 700 at 9.5. And its capable of 22psi. Im sure i. could get pretty close aye? But besides that. Where are you location and whats yal shop #. Ill gladly call you guys.

If you are asking us on what to get, you need to do some more research. It's your engine, and you should be well informed of what's going in it, or should put someone in charge who can make those decisions. I don't care who says the stock crank is strong enough, it's stupid to leave it in at 1000whp, and the D1SC ain't gonna cut it either, there's a reason that everyone making 1k is using an F1. If you try to cut cost by skipping on items, expect to pay later, whether up front or down the road, it'll cost you to make 1000 wheel.

As far as all of the vendors, I don't care who they are or what they say, before I put any of their recommendations to use I put in the time to find out for myself. To this point, I can tell you the limits on every part on my car, and why it made its way on there, I would highly recommend you do the research so you can do the same. Building a car with that power isn't easy, I have found out the hard way.

[JLE58]

The stock crack is strong enough that's why they said it. When you build enough LS engines you will know what works and what doesn't without the google search.

[2SS45th]

Didn't say it wasn't strong, I said it was stupid to leave it in when you are already taking it out, why would you knowingly leave the weak link in, doesn't make any sense.

as for parts. We use Wiesco or Diamond pistons in all our builds. As for the rods the bolts are the weakest link even in after market ones. Luniti, Eagle,and Callies are all brands we use but at a MINIMUM we use arp 2000 bolts

the d1 will not support 1000RWHP you have to think that is about 1150 CRANK hp and that d1 doesnt flow enough CFM of air to do that. Besides that even if it did you would need a TON of PSI and your stock 4 bolt block will not be able to hold the heads down with the PSI your needing. Sure you can get 1000whp on a stock crank and stock stroke. we did it a while back on a Twin Turbo car had 23 PSI of boost to do it and had head gasket issues from day one. The 4 bolt design just doesnt support it for the long run. To do it RIGHT and make something that will hold for a long time you wont want a stock stroke 1000RWHP motor. you will need to get some HP from other means than cramming boost into it. do it right and stroke it, good heads, all the good stuff. Get a cam that works with your combination. get the most out of the motor NA then boost it. Then you can get to your goal alot easier and safer that way. And if you have the coin get a 6 bolt block

If you have any question or what to get a motor built or work done give us a shout we would be glad to point you in the right direction

here is our old shop car. on 17 psi. through a AUTO 4l80 trans and a 9" rear. This is a pump gas car that was daily driven. This was done on a smaller CI motor( 404 to be exact) Through a stick the hp would be quite a bit more. to go from 700hp to-1000hp its not cheap or easy

The other 300 is a lot harder than you think.
