well some setbacks and some progress
first up is one of the brand new injectors went bad, its hung almost wide open.
was out doing some tunning when all the sudden the car started running really rich and rough.he limped it back home and started looking over things.

when he turned the key on and the fuel pump primed u could hear the one injector spraying.

its flooded the hell out of the engine with fuel, pulled the injectors and the company who sold them replaced them no questions asked

pulled all 6 plugs drained the oil.
sprayed a lil oil in each cyl turned the motor over by hand and flushed the block clean

filled it back up with oil and did a compression test 145-155 psi in all 6 holes ,which is exactly were all 6 were before the turbo was installed, so no ring damage or anything

installed 6 new plugs and the old injectors and it fired right up.

anyways got the rpelacement injectors and got them installed and tuned the car some more

on the street ( deserted road out in the middle of nowhere ) car manged a 11.38 second 0-100 mph run prebvious best was in the high 12's, and it pulled the low 11 with traction issues in 1st and 2nd gear.

so cant wait to get it to the track this friday.

the tune is much closer now getting full boost in first gear instead ofter the 1-2 shift

heres a graph of the 0-112 u can see were the car loses traction in 1st and 2nd

hes still running the 3:23 rear end, should be switching it out for an 3:73 gearset soon though


also the under k,meber setup will be comming out in favor of this log style setup to finish out the race season. he has 2 weeks off from racing in a week and a half and thats when hes going to put the log headers in



once the race season is over ill be building him a set of sweeping foward facing turbo headers

turbos are truly amazing things, for not to much money and with a lil know how and diy fab work u get a huge increase in power

btw if u guys know anyone with a 3rd generation v6 camaro or firebird the setup he is currently running will be for sale cheap once he puts the log headers on

turbo v6 against a vette
run = 13.31@104.7 spinning off the line

[Project89]

heres his second round loss from last night
guy got him by .03 on tree and that was just enough for him to lose

i told him if he ever has to line up against that guys again to dial something rediculous like a 13.80-14.0 and make the guys chase him to just past the 1,000ft mark and then get on the brakes hard

the guy dials low to run in the slower class when the car can go low 11's easy
i guess he gets his butt kicked when he tried racing in the class his car is supposed to be in

also the under k setup is gone started installing the log style headers today

be interseting to see how much retuning will have to be done with the much better flowing log headers on there

[Project89]

better picture of the driver side log

Did I do that welding for you? looks like mine,lol. as long as it does not leak.Let us know how much it improves the car?

i didnt build those, neither did my friend whos car they are going on. he picked them up from another board member on the camaro website. even for flux cored wire i do agree they arent the best looking welds but they dont leak.

they are only going to be on the car long enough to finish out the race season. This winter i will be building some equal length foward facing headers for him out of 321 stainless

[Project89]

log headers installed no crossover conected in this video though

[Project89]

he ended up breaking a bolt on each head when removing the stock manifolds
so tore the heads off to remove the busted bolts



looks like some excessive backpresure from the original under kmember turbo setup


alky is doing a nice job of keeping the motor clean though

sounds alot better with he log header setup then compared to the stock manifolds and y pipe setup

[Project89]

motor is out and torn down the verdict is piston ring gap was severly to tight on the top ring ( .015)
end result is a cracked ring land and broken second ring in hole #6
other then that motor is in damn good shape









looks like its going back together with an .030 overbore moly rings with the correct gap, lil looser on the main and rod clearances , and some modifying of the oil pump to turn alot more rpm

along with the rebuild hes steping up the cam to a 272 grind and he already purchased a gt3582r turbo

[Project89]

its going back together with a down n dirty rebuild.
400 grit flex hone hone job
new standard bore pistons and moly rings
not changing the rod or main bearings ( hell why bother they are nicely broken in and the motor had perfect oil presure and no knocks )
going to machine the oil pump for some added presure and flow for high rpm use

the decision was made to do it this way so a larger portion of the budget could be spent on a better trans/converter combo which is going to be th350 and transbrake

new gt3582 compared to the old turbo

[Project89]

new engine installed lmfao

[Old Fool]

looks like some detonation going on there !

yeah he forgot to arm the alky injection system on one pass and didnt relize it till he was past the 1/8th mile.funny thing is no datalogs ever showed and detonation, and the plugs were always perfect after every pass
we suspect thats when it happened,coupled with the way over tight top ring gap it just beat the second ringland till it broke

when it goes back together the top ring gap will be much closer to .030 instead of .012-.015.

he never checked the top ring gap before he put the turbo on, well just assumed having just a tad over 100k miles on the engine the ringgap would have been wide enough

[Project89]

its on its way to being back together

so far the original tiny a2a intercooler has been removed, going to run no intercooler with meth injection on this for now.

engine is a stock shortblock with his 260 grind cam installed and his good ported heads and intake swaped over from the old engine.
heads have had a valve job + all new springs locks and retainers
engine is in and getting the gt3582 mocked up

this isnt the actualy charge pipe hes using hes just tryoing to figure out the best way to do it
i told him to clock the compressor housing 180* so the outlet points stright up and to put a 90* coupler on it to point it at the tb , then all he needs is one 90* pipe from the coupler to the tb were he can put his iat sensor and meth injection nozzle

[Project89]

its might run this weekend





hes going to fab the downpipe tommorow , only real issue right now is that the 90* fitting for the oil feed line cant be screwed into the turbo since it hits the compressor housing, so need to figure something out there
