Hi guys I am getting ready to install the LT4 Hot Cam Kit and I wanted to see what horsepower numbers I should be expecting to gain? I have C.A.I. and L.T.'s on it presently.. Thanks for the help

 

I am assuming this is going into an LT1. I have the Hotcam w/ mid tubes. Check my sig for numbers. People have gotten anywhere from the low 300's all the way up to 340+. Just make sure you have your basic maintenance taken care of, and you have all the supporting mods and you should be able to get great numbers.

 

mine laid down 355rwhp & 360rwt

 

With just the LT4 Cam and not the Cam/Heads upgrade???

That's impressive for a Cam only swap.

What Supporting mods do you have done?

 

I think at full bolt ons (CAI/LT's/TuneUp/Catback/PCM Tune/ RR's) most people put down 300rwhp through an M6. I'd assume w/ the cam and 1.6 rr's you should pickup around 30-40rwhp. So I can see 355 if you have an e-waterpump or something else.

 

the 355/360 numbers are rare. His setup is a good "combo" which means that his results are not typical.

So yes you can hit 350/350 but its not easy. And for every one hitting those numbers there are 10 who arent.

I would expect 325rwhp with full exhaust, 1.6rr's and a hotcam kit.
A ewp, 52mm tb, crank pulley, cutout, etc are needed to hit 350rwhp

 

since you have to take the intake off anyways..take the heads off and get them ported should definitely get you to 355

 

see sig for comparison

 

i have all the boltons & ported stock heads with 1.6 rr's. oh yea, i do have EWP. but it was thru a 12 bolt.

 

Yea it will be having a CSR electric water pump...

 

Well its better I guess to go into this in a humble manner I see than expecting a 10% chance.... I will be running straight pipe from mac mids, we have no emmisions in our county....

 

How do stock heads flow that are ported and polished cause my buddy had his heads PP and never had them on the flow bench???

 

Whats your numbers on track and dyno?

 

his numbers are 355/360 at the tire.
Porting the stock heads can gain you 5-75 hp. Depends on who ports em and how much time they spend on them
