How much "boost" does a whipple produce, and how much can the stock engine handle?

 

I would recomend doing a search as it's been covered NUMEROUS times already.

 

I don't know the boost, but they are publishing about 200 rwhp and mid 15 sec 1/4 mile times.

That will beat 80-90% of the stock 4 and 6 bangers out there.

 

I did search, and didnt find how much boost...

 

i would think its around 6 lbs of boost .... 7+ you start running into head gaskets gettin blown .... atleast thats how it is with the 4.0

 

I'm running around 5-6lbs of boost with nothing else done to the truck except Dougs tuning which blew me out of the water with what it did to the stock program Whipple gives you..

I put the 2.5" pulley on and it started freaking out, and to me I think it was the 35s being on the truck and with more boost added over what I already had, it just didn't run right..

 

I run that already

 

I do as well.... In a 3.0L though... too much money to get it into 15s without a blower but now when i put my blower on.... ohhhhh boy!

 

correct stick with dougs program completely and dont run a underdrive pulley with stock gaskets...

 

yeah sorry little boy, when you a run faster than me in a 3.slow then I'll admit it, we are planning a trip to the track come november when it's nice and cool and I'm calling you out, be there. I'll show you what a 4.0 can do.

 

lets go! Its on... and ill be there WITHOUT my whipple installed

 

Hrmmm.....this will get interesting.

I think I've heard Doug say he's hit 12 pounds of boost in his truck before.

Stock, I thought it was in the 8-10 category. Must be wrong though.

But a 3.0 with bolt-ons will NOT beat a reg. cab SOHC Ranger.....sorry. I've seen reg. cab 3.0s run a 15.999x in the 1/4, but reaction time was his friend.

My personal best was a 16.4.....but that was in "race trim".....aka maybe a gallon of gas in the tank, no spare tire, a good 20 mph tailwind, etc.

My truck REALLY needs to be blown......BADLY. It would really round up the whole Saleen theme properly.

 

John, don't give credit to reaction times. It has no effect on 1/4 mile times.

 

I never said I could beat a SOHC reg cab in anyway... Can I run 15's?!? sure can.... and in 90 degree weather with the FL humidity. I have spent a lot of money and time on this truck... Back in July I ran a 16.3 on 93 octane tune without my current intake and polished heads... 15's are easy with the new cam and 100 octane tuning as well as the polished heads

 

you on crack......... ......reaction time is key in 1/4 mile. get a 2 secound reaction time compared to a .5 and come back and tell me if you had the same ET....

 

It will be the same. Look guys. This is my thing, it's what I do. Trust me on this one. I can run a 15.9 with a .5 reaction time and beat a guy that ran a 15.7 with a .8 reaction time. I will beat him by .1. I have done it and others have done it to me. :

 

Wayne is right!

 

R/T has no effect on your E/T... Thats how the measure R/T... the time from the light changing, to breaking the beam. If you really want to get into it... Shallow staging will net you a faster E/T and faster trap speed because your esentially getting a run at the timing lights...

 

^^ yup..nothn matters till you trip the beam
