Makeing 430 Rwhp Already Thru 4000 Stall Unlocked And Havey Drivetrain

Gonna Spray Anther 175 Rwhp Is This A Bad Idea?

 

Is this still the stock short block? If so it most likely wont last very long

 

It will hold for a while. Just dont spray a 175 shot every time, but with the right tune and enough octane you should last a while. good luck.

 

you will be fine just have a good tune, and read your plugs

 

Make sure you have good oil pressure, and if you can I would run a nitrous tune with the timing cut back 4 degrees.

 

What are your mods?

 

5.3l heads ms3 cam intake and every other bolton

 

This Saturday I plan on running the 100rwhp shot, and will probably step it up to 150rwhp. I'll be stopping by a buddy's house this week to pull some timing out, I'll be running 100-octane unleaded, and BR7EF plugs gapped at .032". Sunday I plan on putting in the 200rwhp pills. At that point, I'll have some 112/116 in the tank along with the 100-unleaded and probably a bit more timing pulled.

If it blows on Sunday, it blows. I've got a trailer ride back home

stage 2 cnc'd 5.3 heads, 224/228 .641/.646 110LSA, fast90, full bolt-ons, racetronix fuel pump + hotwire kit, fuel solenoid screwed into aftermarket .582" ID fuel rails. Single nozzle fogger setup with NX Ice Man solenoids.

 

You're making 430 to the wheels on motor with those mods through a stalled auto? If so, those are good numbers, and a 175 shot will put your stock bottom end past its limit. It might last a little while...but not long. You have to figure, your motor is going to be making close to 700 hp on nitrous, if not more.

 

How Far Can I Go On 93? I Gonna Have To Limit My Shot To Whats Do Able With Pump Gas

And Yes 431 Rwhp With Those Mods And Nice 95 Deg Fl Summer Heat Via A 4000 Stall Unlocked...

 

Thats a big shot!

 

I wouldn't go that big on 93 at all. That's just asking for trouble, especially without pulling any timing.

Are you going to have any timing pulled?

Were you going to run TR6's or BR7EF's?

I'm going to pull timing probably 4* everywhere, and run BR7EF's with 100-octane for the 150.

For the 200, I'll probably pull another 2*, run BR7EF's, and a mix of 100-octane unleaded and 112/116 to have it somewhat close to 110.

If I'm losing out on power, so be it, this is just the final hoorah for the shortblock before I tear it down this winter and forge it.

 

There is no reason it should blow, i was sprayin my stock short block off the trans break all last season with 125-200 hits. My motor loved it, never blew i sold it to a friend and its still goin. Have you run the car on motor what kinda of #'s did it turn cause thats some good power

 

Adding 430 and 175 i get 605, not close to 700.

 

I think the 700 was engine hp. Yeah let us know how it goes. Good luck. If it hold it should fly.

 

Yeah, I didn't mean 700 to the wheels. 605 to the wheels through an auto will be damn close to the motor making 700 if not more.

 

93 octane is good enough for a 200 rwhp shot as long as your tune is good. I have done 20+ passes on 200 rwhp with 91 octane and 22 degrees at wot. Also I use tr6 plugs.

 

At 600 rwhp your at the safe livable limit, given all tune parameters and fuel are spot on. If so, yes it can live for some time, though, one glitch could spell disaster, but sounds as your prepared either way. Good luck and let us know how it turns out.

Safe Limit --hell Yea!!!

Robert, I Forgot To Mention This Will Be A Dry Shot From A Nitro Dave Halo

Im Thinking To Spray At 3000 Rpms Starting 2nd Gear Shift At 6700 (current Shift Point N\a For My Ms3 Cam (rpms Limited By Stock Bottom End)

 

Also Im Thinking Of Having A Halon System Plumbed For The Engine Bay Before My 1st Run
