My GT Cont.

Haven't posted in a while, progress since the new motor has been in is slow. first dyno pulls without tuning 334 rwhp @5400, and 353lbft@4500. The cam is designed to make peak power at 6000 and shift at 6500, unfortunantly the car started to go lean at about 5600 and by 6000 was running 14.17 a/f. Put in new injectors and am still waiting (6 weeks now) for a new mass air, they are on back order. Then will start the tuning. I drove it around and got on it a few times shifting at 5500, car fells very torquie for a lil 4.6. Ill post again when things are done.

Sweet good to hear!

[DustinsDuster]

334rwhp from 281ci without a power adder is pretty badass. cant wait to see it on the spray!

[69gt4speed]

I really think it will go 360 whp with a decent tune/fuel imo at least on that dyno.

[amoander]

I doubt it would post that much Rob, but it would be awesome if it did.

[NewSpeedSteed]

Glad to hear that your still making progress- even if its going slow. Can't wait for the numbers after a good tune.

[vr4rider]

Yo, Adam.

Congrats on the numbers. You told me over the phone, but I thought I'd congratulate you on here, too.

I can't wait for spring/summer. I wanna tune my bitch (get my WB hooked up) and line up with ya:)

Get at me when you get your car in IC.

[Domestic Disturbance]

Can't wait to see it all done and out. It'll be a lot better than the last time i saw it

[stangvortech]

OO Yea, I was going to ask you if you every figured out why the battery died after the last run that night at cordova?? I just though it was weird?

[69gt4speed]

Right here. What else Adam can tell ya.

[stangvortech]

I know about all that that I was there when it happened. LOL
I was just wondering about the battery thing?

[69gt4speed]

engine was locked up. Hence it would not turn over. Thanks to Jeff we were covered.

[amoander]

Final Diagnoses was the rod cam apartand loged the rod/crank against the block wall, pieces of the pistoin were found in the intake, and half of the rod bearings were spun, hence i couldn't resuse the block. It wasn' detonation from what I or anyone else could see(probably was some though). The weak spot in my engine is the rods and they tend to come apart like that, if it was detonation we would see more piston issues, pistons were beat up but didn't look that bad. Obviously the heads wer messed up. Can't remember which cylinder. Think is was 4

Is your motor a 2v or 4v?? What all do you have done to hit that power and what kind of dyon was that on?? From reading other forums most people with H/C/I and other bolts on like LT headers, tune, etc only hit around 300 rwhp.. I'm just curious cause I'm debating on what to do with my mustang that I have right now.

Its just a 2V 4.6. In my opinion, f/i is the way to go with 2V 4.6s the n/a route for any mustang is the expensive one, especially if you want to make over 350whp. I'd almost say it wouldn't be possible, but thats not true... it would just be such a bitch to drive (no low end power, and it would need to rev to 7k to make decent power) plus in the long run supercharging is cheaper. But its your call.

I agree with ya there, f/i on a 2v is the only way to go. The 2v motors respond to boost very nicely. I see a lot of people posting running anywhere from 350-400 rwhp on stock componets with a good tune. The 2v motors can handle a lot and if you get it right make upwards of 700-800 rwhp out of them fully built. It takes and costs a lot but that's a lot of power out of a small motor.

[69gt4speed]

I see a lot of people posting running anywhere from 350-400 rwhp on stock etc.

the issue I have w that is the rods/pistons go poo poo w any issue at all. You might have it tuned good and everything for 93 but u get a bad tank of gas and it goes to pieces. To get a stock 2v in 400 whp range u need 10 to 12# of boost w a cent s/c. W 10.0 compression they run good w a centrifugal, I've raced a few but one tank of bad gas running that close to edge it will be toasted. The rods go usually. I'm not going to point fingers but it seems mighty funny that Adam put some 93 in at cordova and poof. Gas might have been old or whatever. Phatsvt w his 2v vortech at 11# same deal. So I have no confidence in those rods w any issues. They don't call those pistons hyperpathetic for no reason. After research of the 03 I was satisfied it might take some abuse mo than the others though i hate the insurance rate.

[NewSpeedSteed]

I've seen alot of GTs run 8psi through a Vortech, KB, Porcharger w/e (with a good tune and injectors, a BAP occasionally) and have been problem free for 80k. But I agree 100% with you Rob that the stock rods and pistons are pos. I would imagine with full exhaust, and a few other supporting mods you could break 400whp on 8-10psi. I'm glad that I have a Mach, my internals seem to hold up better than GTs do. Even though the only thing forged is the crank, I just feel more confident that I could run 400hp without having an issue. In short boost or nitrous does not kill an engine, detonation does.

[amoander]

Lot of rumors and BS about the 2V, yes the heads suck, but they can make decent power. Enjoy.

watch any of the videos from speeds8erM1 some low to mid 400rwhp 2Vgt's

I have the same motor as this but stroked to 5.0, if you read the articles with alot of tuning he has now put down 345, he has also added a blower and changed to a blower cam.

i agree with Rob, i suspect something with the gas, but we will never know for sure.

[69gt4speed]

Well i know for fact phatsvt went 11.9's, it was tuned by Jerry Wroblewski of sct ran 1 yr this way till that day. He had cobra 39# injectors, the twin cobra tank & pumps, 03 cobra maf. He had it dynoed again shortly before my lil k.c. test w him. 426whp on a dynojet. He pushed it to 12.5#. Almo had almost same setup. I don't remember if 426 was std or sae. he wanted to beat my cobra, dinner for 2 was the bet. Sam paid it and sent me the video... first class guy.

[amoander]

my et will be crap cause i won't be hookn up on spray. good points Rob

[69gt4speed]

Well i was talking to my friend. He is just getting around to getting his gt together.
What it will have..---cast iron block bored .020" (3.572"), forged cobra crankshaft, Manley h-beam rods, manley flat top pistons with no reliefs, 2V pi heads, Ferrea valves, comp cam beehive springs, Crower stage 2 camshafts---
I would suspect it isn't stock heads. I'll ask him where is the s/c etc?

[amoander]

That would be a fun race

[69gt4speed]

He's a good driver, not some old tard like me.... :bigthumb:
