It wasn't actually BOOM. But that sounds better for the subject of the post!
It was more SMOKE than anything.
My bro in law has that 318 we had been playing with a turbo on for a while. He was limited to 5PSI for a long time because of no extra fuel.
So he calls around and buys and installs 39# FMS injectors!
We grab a approx 2 Bar MAP sensor. The PCM needs to be modded for this but it actually worked fairly good.
Now he was more RICH than LEAN. And it was pulling hard as a mo fo the other night.
SO this morning we go to get a new cat. The 2 1/2" was so restrictive that it blows the pipe and cat off from a clamped connection from the 3 1/4" down pipe!
He installed the higher PSI spring and shims into the waste gate and we now have 9 PSI.
The stock PCM hits the rev limiter so many times. I think that was really bad.
We blew the head gaskets something aweful and hopefully nothing more!
Anyway. Not to type everything twice. Here's the story, pictures, and videos I posted on my website ---> http://www.paysonarizona.net/cgi-bin/yabb2/YaBB.pl?num=1157846721/0#0

I have yet to see the smoke but Im sure it will come real soon for me. I bet he blew them out due to detonation. Read the plugs and see if they are fried. Im running a MSD boost timing master that allows to retard timing per boost.
Once you guys get an inline pump and FMU you should switch to maybe 24# pound injectors. You would be running way to rich with those 39#'s. Im running the 19#'s and a 12:1 FMU disc. Also go with the MSD fuel pump. I have about 60psi with the pump on at idle. And Im sure its close to 100psi at full boost.
The popular head gaskets for boost are the felpro 1008's FYI. Im still in the planning for a turbo project but it wont be awhile till I get out of school. I already have all of the hard stuff done.
Here is a diagram I drew up of my fuel system. I can be done for less than 300 bucks.

From the video it seems like that trucks dam quick. It hit 80 pretty fast. I think hitting the rev limiter was due to the fact with him messing with the shifter. Lol.

Yes, the shifter had lots to do with it!
The rev limiter was probably half of the problem for all I know.
I think he broke the 400HP mark on that 318.
Damn pu$$y limiter in the 318 LOL!!
He removed the SuperChips programming and sold it due to he can't use the timing advancing!
Funny, is he has a good Cam and double coil springs. His top end should be capable of 6500 RPM's no problem. He needs a PCM programmed.
For the timing, I am getting better at programming micro controllers.
Give me a few months and I should be able to build a controller from scratch to put in between his PCM and coil to retard spark per RPM's and Boost :)

This makes me want to ditch the S/C and go with turbo. That 9#'s with the turbo is probally making the same power I would be making with 13#'s with the supercharger. Except for the fact that mine is somewhat tuned...lol. What would really help now would be a M1 and a F&B TB. So far I have the 58mm that I got a good deal on. Im going to be ordering the 4bbl M1 this week. I want to upgrade the valve springs to handle 6k and get it flashed. I think as is I could be in the 12's with a 3k stall and a good launch since I already have a 101 mph trap speed....and thats with a 2.3 short time.
Heres my 58 F&B, Im ordering the M1 this week but Im going to wait to install it after I make the 500 mile trip to PA for school. I dont wanna be sitting in the middle of the gigantic limestone walls with a coolant leak.

Nice. I could only imagine his 318 in YOUR gen Dakota! His was wanting to bust the tires loose when it built boost.
Those felpro gaskets you mentioned. Are they THICKER to lower the compression as well? Or just stronger gaskets to stock specs as far as thickness?
We talked to some guys tonite at the track. They seemed to think 9 : 1 area compression would still be ok with the turbo.
Oh, a cool car we saw tonite was a Ford GT 40. 5.4 SuperCharged Mid Engine. Just when he was about to dip into the 11's it started to smoke the clutch! There was a Viper (modded I am sure) that dipped into the 11's. Sounded like all motor.
The GT 40 goes for close to $200k so it better be damn fast!

Im not sure if they are thicker but I know they can take boost. They are steel reinforced, check them out here.
http://store.summitracing.com/partdetail.asp?part=FPP%2D1008&N=700+115&autoview=sku
The part number is actually for the old LA blocks but they work on the magnums. Dave Downings said he has run 15+ psi with his paxton and they held up fine, and he also putting out 3 shy of 600 RWHP (yeah thats rear wheel.) He is also running the mopar 360 short block with 9.1:1 compresion..so 9psi should be just fine.
If hes got money go ahead and throw on a set of ported magnum heads with 2.02 intake valves. They have 60cc chambers so the compression will stay the same. They are only about 2k....hurts to think that you could build a 500hp chevy for just what heads cost for the magnums.

He don't got the $$$ for heads right now. He was thinking it would be cool to get them though!
Dude. Those gaskets are more liek it. $38 each!
When he looked on line, the sets are $140 or so!!! I'd hope they came with the entire top end for that!

this is my truck. itwas pullin hard until the rev limiter hit. i think we should be running with a 100+mph in the 1/4 mile.i have a chance to buy a greddy e-manage for $300 and will piggy back to pcm and controll ignition and fuel. i was told it is compatable w/ obd2. i just need to worry about getting good gaskets first and get it running again.
i also have a deal working for an greddy electric boost controller and can select from diffrent boost ranges from driver seat and how fast it switches between the two settings. you know keep boost mild while towing and higher for fun!!!!!

i was just looking at hughesengines.com they hace conetic head gaskets that are multi layer metal. my brother in law has those on his silvia running 14lbs boost on street w/ pump gas and 24lbs on race fuel and he has little over 8.5 to 1 compression with out any problems of pinging. so i think i might go that rought and lower comp. down a little so its a little safer for boost. boost is addicting, you start low then you want more and more all the time. i think i will be happy w/ about 10lbs for a while. god knows i have enough fuel now

100+ is a good goal at least. Compare your truck to this video of mine. Im running 101mph with a shatty 2.3 60 footer. In the video 100MPH is about 96 on the speedo since Im running larger rear tires.

How many miles do you have on the 318 Rammer? I just hit 142k in mine and its running stronger than ever. Im ordering the 1008 felpro's tonight along with the 4Bbl M1 Manifold.
How long did it take you guys to do the gaskets? Im planning on it not taking more than 2day doing it by myself.

we havent put it together yet. i have it apart i should do it right.i found a place called fbo that does multilayer gasket for $129.95 a pair and they are reusable.they can custom make diffrent sizes for comp. ratio and engines.
another place is cometic gaskets part #c5554-040
for thicker its a little more $$$.
so ill be on phone first thing in a.m. to find outpriced
i know the truck will hit over 100mph it already was about 84mph before turbo, and cam, and porting the sh$t out of intake.

Ah..so thats actually a pretty light truck. You should see some great times since you got the 4.10's as well. I put a powertrax in about a month ago and I love it as well. I think its the best mod I have done.

you said youre running an msd timing retard?
where did u find that abd how much? so ur running 13lbs boost! thats sweet do u have an intercooler? i got one from an 98 ram diesel, its definetly big .only get about 1-2 psi drop across it!

Im running about 9-10 psi. I was stating before that with your turbo setup your probally making the same power if I WAS running 13 psi. Im not running an intercooler which is really killing my power. But im working on that... There is like no room to put a front mount on my gen II so I gotta figure something out.
The timing retard came with a the used kit I bought. its a MSD BTM and the runs about 200 dollars. I run 93 unleaded and I have the death flash so I dont get any detonation with it set on 0. I set it to 1/4 per psi to be safe though. I seen your intercooler and that thing is huge. Probally really to cool down the charge.

We ran the thing on the street and pulled over as we were playing with it. The inlet would be hot and the outlet the same temp as OutDoor.
From what they are saying on the other forum, he should install the FMU and auxillary pump to fix the fuel problem. Or it's always going to be running rich at idle/cruise and set a code.
The 9.1:1 may be ok after all if the tuning gets fixed.

Thats correct. 39# injectors would be good at boost only. Idling and cruise is probally running way rich. Like I said I would go with a 12:1 disc in the FMU or better yet since your gonna run an adjustabe wastegate might as well get a adjustable FMU to tune. Aeromotive makes a nice one but they are a little pricey. Also the MSD fuel pump is what Im running. Cost about 90 bucks and supplies plenty of fuel at a nice pressure.
One tip...dont skimp on the fuel line. Go ahead and buy the 5 dollar a foot fuel injection line. I went through about 30 bucks in shatty fuel line before I broke down and bought the good stuff.
I wish my oulet was the same temp as out door. You touch my airhat for a split second and your hand will blister. It was funny at the track I had my hood popped. ...And a natural reaction for a lot of people for some reason is to touch shiny things. Usually I would get very angry but I enjoyed watching several people burn the piss out of their fingers. Gave me a good laugh.

If you are not wanting a custom fit intercooler, or home made one...
Go look into the WATER/METHANOL injection. It supposed to drop it like 60 degrees in temp!
People buy the Windshield Washer Fluid with the real METHANOL in it. Napa sells it. I guess you inject that stuff through a squirter and it works! Just got to play with how much and only use it on high boost so it lasts :)
