My car + some Boost

[justinschmidt1]

So Im pretty sure Im gonna get a blower within the next year or so..

Just wondering how you guys think my car will react...I have pretty much every bolt on for the car and I plan on running 8-10 psi intercooled centri.

My car ran 14.1 at 102 mph...spinning with a 2.25 60 foot on street tires. I would imagine with some sticky tires I could be pretty deep into the 13s..

What kind of numbers do you think my car would throw down at the strip?

I was thinking with some slicks I could be deep into the 12s with a trap speed over 110.

You'll be running what I run. 4's at a million.

PI cams are decent plower cams, throw some in with a Vortec and you should be able to see the bottom 12's pretty easily.

 

[justinschmidt1]

wonder what Ill run without pi cams haha.

Thats pretty much the exact same setup im running. Full bolt ons, Vortech sq trim, paxton intercooler, about 11psi. I see 370rwhp, 380tq but keep in mind thats through an automatic. I am doing cams next and am hoping to see around 410rwhp. Never been to the track so i couldn't tell you what she runs.

 

[justinschmidt1]

Ive got an automatic...whats your full bolt on list?

 

[97stanger]

Well to make it easy here is my full mod list:

Vortech SQ trim with supporting fuel/spark upgrades
MPH boost pipe
3.12 pulley
paxton intercooler
vortech mini race bypass
pi intake manifold
slp longtubes
slp off road x pipe
slp catback
accufab 70mm throttle body/plenum


I think thats about it motor wise...All this is tuned by SCT

 

[justinschmidt1]

I thought you had cams too?

were pretty similar in mods other than the cams.

You have a AWESOME car.............auto FTW 8)

thanks for the props!

And no i dont have cams yet, will be ordering custom grind cams from MPH in the next week or two. The 370rwhp/380 is through everything you see listed...still running stock non pi heads/cams!!

 

[justinschmidt1]

ok, gotcha...I remember reading about you getting new cams or something..

But yea we would probably be similar in dyno numbers.

What kind of boost you running? 9 psi?

I plan on running 10 psi intercooled.

 

[97stanger]

more like 11-12psi...im running this much because i planned ahead, knowing that the cams will drop me another 2-3psi. smart huh?

 

[justinschmidt1]

ohh..haha..So Im assuming its safe to run 11-12 psi with the npi heads or what?

Ive heard its safe untill 450 whp.

 

[97stanger]

well i would never run more than what i am, but i know its not boost that kills these motors...it's the hp limit.

 

[Jrgunn5150]

ohh..haha..So Im assuming its safe to run 11-12 psi with the npi heads or what?

Ive heard its safe untill 450 whp.

In the 400 rwhp range you are nearing what the stock rods want to see. 11-12 PSI is safe, assuming the tune and fuel system are also safe.

 

[95PGTTech]

et/mph weight calculator says
3700 lbs.
380 hp (does not specify whp or chp)

12.44 @107.72mph

I believe it.

+1! Just make sure you have the supporting mods to be able to handle the blower and its boost!

 

[justinschmidt1]

fuel pump, injectors, tune?

 

[Jrgunn5150]

Yep, your basic LIghtning 42lb set-up is sufficient, 255 lph pump, and at 400 rwhp, ur good.

 

[justinschmidt1]

Question, This dude was running the a pulley supposed to be good for 15 psi at 6k..

Ive heard that the long tubes will reduce boost by like 2 psi.

Maybe the pi intake will reduce the boost.


I hope with that pulley to be no higher than 12 psi.
