i currently have the 5177 NOS dry kit and i've always wondered why dry kits come with only 100hp jets (max) and wet kits come with higher hp jets.

i know you can just buy bigger jets but it seems theres gotta be a reason that the dealers dont include bigger jets with the dry kits.

is there something i should do to my kit for a bigger shot or is buying bigger jets simple enough?

i hope everyone understands what im trying to ask.

thanks in advance

 

it's because stock injectors tend to max out with shots over 100 - if you want to spray more, go with bigger injectors and an upgraded fuel pump

you may be able to get 125 or 150 shot out of it off a stock fuel system on a car making stock power, but make sure you are monitoring A/F, knock and injector duty to make sure it is safe

 

okay, injectors had crossed my mind so i've got a warlboro in tank and 36#ers. i will installing these in a week or so. now, what kind of jets can i look forward to getting?

NOS claims their 150 jets give approx. 120 rwhp. what are some opinions on jet size considering i have the pump and injectors (36#)?

 

no one else???

 

You can go all the way to NO JETS

 

I ran no jets in my 5177 for 2 years.

 

and no jets is equivilent toooooo.....??? (how much power)

walker, what sort of equipment did you have to support this "jetting"? remember i'll only have 36# injectors and a warlboro in tank 255.

 

Becareful on spraying over 100 using a Dry shot. I suggest a Tune before you attempt to do so. could save your Car

 

yes i highly suggest a tune before you go over a 100, and beside w/ 36lbs injectors you need a tune anyways. btw i motor went of a 150 dry. and when i say went i mean i had hole through the block.....

 

thanks for the info, but dont discourage me dammitt.

 

I sprayed no jets for a while also. Never got a number of how much I was spraying though. I was running 28lbs injectors, stock fuel pump & TSP's mail in tunning and never had a problem. Its not the smartest thing to do I admit though!! When I first tried no jets on stock 26lbs injectors I got alot of popping and denation after I went to the 28lbs it all went away. Hope this helps............

 

I ran the 125 jets with full exhaust and a lid....it made 438/504 with stock injectors, stock pump, and stock tune, didn't go lean either Equated to a 101rwhp 155rwtq gain. I am gonna get 42lb injectors, fuel pump, cam, and tune of course and take the jets out. Shooting for 150rwhp, 200ish rwtq.

 

yummy, now we talkin.
