yes im pretty positive that you cant get 400whp out of a 2871r with out over spinning the **** out of it, and youll have a pretty similar thread like this one down the road

a 3582r on a 2.0LSJ on 18-20psi put down 385whp..... soo yeah

 

^^^ thats massive and it should have hit higher than that. my 55 trim is just fine for 400 and its alot smaller than that.

 

what kit are u getting?

Or is it custom built?

 

i dont care about what the car could hit for power, no kidding it could have made 650whp, im talking about the most efective range for the turbo, 400whp on the 2871r is MAX, and your running thin lines doing that, which alot of people do, but myself, id rather have a reliable setup

 

we shall see in 2 weeks.. worst case sencario ill save up and get a 6262... but the owner of the kit im gettting it from dyno'd 363 on a stock lsj on 15lbs

it was custom built by another member should be coming off his car tomorrow

ok cool thanks man.. so i should just give a quick run through ?

 

instruction will come with it, iirc it was 20 strokes on high speed and 7-10 on low speed (hand held drill). if you look for youtube video of hand honing it will give a nice demonstration!

 

in for rebirth numbers

 

alrightyh thnx man

 

sub'd for updates

 

nice progress

 

thnx.. didnt get anything dun today too tired... been flagging 55 hrs at wrk. but i didnt order my stg3 clutch. ttr ftw ! by the way guy i decided not to build the head. just gunna have the maching shop rebuild for 150.. new valves, seals, and hot tanked, because i need an exhaust, open down pipe might be a bit to loud haha

 

The design of the top of the piston can help with the propagation of the flamefront and also effects quench. Improper piston design can result in hotspots which can cause detonation.

This project is great let me know when you get it done and you can come up to boca for some racing.

I think you will hit 400whp with the aftermarket head and cams. Definatly if you add meth. But like everyone says that turbo will be working hard. 400whp is optimal range for a gt30 not a gt28. good luck

 

than k you for clarifying i didnt know specifics.. i just knew it could cause it

 

thanx for clearing that up.. after doing a lil more research ive realized the turbo isnt big enough to hold that much power efficently and is going to start glowing pretty quick haha.. so ill probably upgrade the turbo to a 6262 or a 6057 from precision.. but thats in january some time lol... i really wanna get a meth kit but they are a little pricey and i really dont know how it works lol.. never researched it.. but yea man when its dun ill take a ride up there. im always down to do some "closed road racing" lol

by the way does anyone know how much psi a 2.4 intake mani can stand before popping lol




also ive decided since no one wants to buy my nitrous kit im just going to use it as an intercooler.. but insteasd of filling it was nitrous ill filled it with c02 ( cheaper)... has anyone run intercooler spray on their cobalt ? feedback on idea ?

 

the 2.4 intake manifold can hold alot of psi i know someone took it up to 22 psi and it held .. zzp had their turbo 2.4 at like 15-17 psi or something as well

 

oh ok sweet.. not sure how many lbs of boost im running but i dont think itll be more the 19.. w.e. my tuner says lol.. i started honing the cylcinder walls today.. they were actually in really gud shape, justhad to touch them up.. also ordered new rod bearings. so the bloack should be back together by tomorrow afternoon. and the head went out to the machine shop. that also should be in tomorrow. then i can slap the motor back together and then i just need to wait for my turbo to come in

 

Turbo and other parts shipped today!!

 

sweet... yo kennyspec is the f@@kin man !!!! i drove him crazy the past few day with a **** load of ?'s at all hours of the night hahaha... 5 stars for a goog guy

hey guys meth or e85 ?

 

How much you want for the nitrous if its the right price I may know some people? And meth is really good idea especially with that much boost and 10:1 CR. Pretty much you can buy the pure stuff over on prospect next to 95 at the VP and you mix it with water and your good to go. You dump it into a tank and the set it to turn on at a certain boost level. The more expensive kits can even add it progressivly. it raises the octane to between 100-125 depeending on how much you inject and it lowers your intake air temp 50-60 degrees. And it lowers EGT's and combustion chamber temps a few 100 degrees and the steam from the water cleans all the carbon deposits off the head and pistons. Honestly im boosting my vette next month and meth will be the very next mod as a safety thing. As long as its set up right you won't have issues its when people don't set it up right bad things happen it's like nitrous the horror stories are always from a guy that screwed something up. The only thing you have to worry about is to keep the tank full. Most kits come with a low level senser and the high end kits will open your bypass valve or wastegate if it doesnt detect meth flow so you can't build boost. The kits range from $200-$800. VP pure meth is $37 for 5 gallons here

And imho the intercooler nitrous spray is a complete waste you would be better off putting a 10-15 hp shot into the motor that would cool it alot more. IDK how your set up is going to look but if the air intake is anywhere near the intercooler it can suck up those gases under WOT it has a powerful vaccum. I would only use it during pre staging.

Last I checked the only place to get E85 was miami and stuart.

 

to be honest i wanted 450 +shiipping but ill take 350 now for my nitrous kit... its 100% complete kit.. yea ima jump on the meth ill have pics of my motor after work today.. thnx forthe info man

 

yeah nitrous kits suck to sell. no matter how good of a kit it is, no one wants to pay for it :\

 

yup and i can use some extra cash right about now.. how ur build going ?

 

no prob

If you don't mind could you post up or pm me the
brand of the kit
what specific kit in that brand
and what accessories (window switch, purge, etc.)

Just so I know what to tell people I got a few friends going with spray this winter.

 

its going all right. some minor set-backs here and there. i had my clutch fail so it was like a grand taken away from the project. aiming for a late january install but thats probably not gonna happen. lol

 

I know what you mean the kit I got on my corvette is a straight up race kit it cost me $1700 and Im only selling it to this guy for $600. it had All your basic stuff that comes in most kits and

A 15 hole perimeter nitrous plate.
Noids good to a 500hp hit
Fuel pressure safety sensor
oil pressure safety sensor
duel lighted purge
nitrous filter
A hidden switch panel
blowdown tube
autometer Nitrous pressure gauge
Standalone nitrous computer with window switch, wot switch, gear lockout, progressive control, lean and rich A/F monitoring with a safety system to shut it down if it went either way, lean out delay, nitrous solonoid delay, pedal delay, and time delay and timing control to only remove timing when I spray.

Nitrous never got over the stigma of being cheap power so people want it real cheap
