How Many Of You Have Hit This Mark On A Stock Bottom End..

What Was Your Combo?

How Lond Did It Last?

How Often Did You Spray?

Ie:

Im Looking To Spray My Way From My 430rwhp On Motor To 600 With A Single Stage Dry 175 Shot

My Current Mods Are 5.3l Heads Ms3 Cam And Full Boltons

 

good luck with that. I know it can be done, but I also know that it does have risks and you should be able and fully expecting to buy a new short block at the drop of a hat (or push of a button). I have N2O dry shot installed on my car right now, and have decided not to spray it because it spun a bearing ON MOTOR on the 1st dyno pull. Its ok, I will eventually spray it but not until I can afford it.

That being said, have you considered starting out small. Start out with a 75 shot, and then bump it up to 100, 125, 150, and then 175 (maybe less steps). This is how most people who do it. You also should be aware that you will need a fuel pump (boost a pump) not to mention 42 # injectors. Good luck, and nice choice with the dry shot.

 

^ how is a dry shot a good choice?

 

Here's my ? what are your goals? a 600hp car? a 9sec car?
Yes, I'm sure someone is running a 600rwhp car on stockblock. And yes, someone is running a 9 sec car w/just over 500rwhp on stockblock aswell.

 

My Goals Are 600rwhp.. Then To Build A New Motor For 1000 Rwhp

Thanks For Your Replies Guys But Lets Try And Stick To My Actual Questions

 

I agree about bumping up the shot. There are plenty of times that shots yield larger gains than their ratings. A 150 shot would be safer on the stock bottom end, and may get you where you want to be (or very close).

 

thats would i would like to do with my car as well man. hopefully make close to 600rwhp on spray!!

 

Why would it not be a good choice?

 

This is in reguards to this mans thread as well. I heard that even with a 85mm MAF, bigger injectors and lets say 150ish dry... The 85mm MAF is basically maxxed out CFM wise at/around 450 on motor, to where its a tuning issue trying to introduce 150 dry through the MAF even with a large fuel pump and injectors. Has anyone ever heard of this issue? Was i lied to? Also, should you descreen the 85mm MAF when doing a sizeable dry shot?

 

Good luck with a dry shot. If you tried a wet 175 you might do it. If you have a stock tranny and rear better have a tow truck for the ride home. A 150 dry shot is risky, no way with a 175. Back in 1999 I ran my car with 150 wet shot on stock everything ran 11.70's. The 175 shot was to much for the trans.

 

You should speak to your tuner.

I make 410 on motor,stock maf, and spray 175 with a dry kit. It's all in the tune/tuner. No problems with the maf / scaling it.

 

very nice! any issues with freezing the MAF's screen?

 

You should descreen the MAF. It will freeze up.

 

i should be there soon...heads/cam stock bottom end and a 150 shot...im hoping to be over 600 actually...

 

My car with H/C and 100 shot just made 585/592. I used a NOS 90mm plate kit. The car did 440/400 on the motor. So it gained way more than advertised. Also what mods do you have to your fuel system ? I have a racetronics pump and 42# injectors and I am out of fuel. I wanted to try a 150 shot and go for 650rwhp but I need another fuel pump.

 

fuel system, and drivetrain are good for well over 600 rwhp... but if you wanna know

flt lev 5 tranny
midwest 4000 billet stall
3.5"chromolly driveshaft
strange s-60 rear
chromoly everything suspension
racetrnoix pump had wire kit
42lb injectors
and just about every dam bolton on the planet (besides a blower)

i will be using the hsw interface to add/correct fuel and pull timeing

my kit is a single stage halo kit with all the proper saftey stuff


simply put this is no budget project im prepared to buy a new shortblock in the future but i am tring to get an idea how long i can expect a 150+ shot on a already strong h\c car will last

i will be pulling atleast 6 deg timeing and shoot for a afr of 11.2-11.5

only bad part i guess is it has to do it on 93 octane

btw i have a wideband in the dash too!

 

He said good choice on the dry shot. A good choice as opposed to what would have been a better way of wording my question.

 

I dont see you having any problems with hitting the 600rwhp mark, but i don't see the bottom end holding for very long. You might get lucky and get a good amount of runs out of her, before you decide to change out the block. Or maybe on the first hit the engine says "WTF" and just takes a **** on you. I believe with the proper amoutn of fuel, and a wet 150 you should be able to surpass 600rwhp. Have you check out the Dynotune A/F shut off safety switch, seems like a pretty cool product if your spraying and your A/F takes a dive.

Nope, Injectors are not close to 100% either.

Aeromotive in line pump, svo 42lb green top injectors...and my screen has been taking out.

Then, when you get a competent tuner... you go to direct port dry kits.

 

Awesome, thanks for the info. Im going to descreen my 85mm MAF and score some 42lb injectors before i hit the dyno. Im going to try for a 125-150 shot and see what happens! I currently have 30lb injectors, but ive seen a few members on here maxxing those out around 450ish on motor! I also have a magnafuel EFI pump to ensure plenty of fuel!
