This is the OD problem that comes up in Kill stories when guys try to run LS1's from a roll above 120 mph,
The 3-4 shift, if left to the transmission, will kill the cars forward momentum. If you wind it out in Drive to 5300 RPM or so and then shift OD it should run zero to 130 way quicker than 30 seconds.
My Pontiac 2+2 ran zero to 157 mph in 32 seconds and I know for a fact that a recipe modified TTA would be quicker (an aerodynamic 12 second/115 mph car = about 0-150 in 25 seconds)

Thanks for the replys! I read that again today. 130mph in 30.2 secondsI'm trying to decide if I want to get a TTA or another Gn next spring?????
The original Car and Driver Road Test for the GN in 1986 was equally screwy (except to 110 and 120 mph):
1/4 mile: 13.9@99 mph
100 mph - 14.4 seconds (good so far)
110 mph - 21.8 Seconds (WTF????)
120 mph - 33.1 Seconds (double WTF???)
I'd bet money the test car was pulling timing like mad on the OD shift from knock, the boost dropped off and the car struggled to get it back together.

That is definitely in the ballpark. I read that a 99 Z28 did the 0-130 in about 30 seconds also which is moving quite fast for a stock car. even if you held onto 3rd gear and not let it go into O/D, it's not going to do it much quicker because the engine will be out of the powerband soon after 120.
These heads are not the greatest for breathing up top. They actually flow like crap, but that's another story. Even in O/D, if the heads & intake are flowing, it will still pull like crazy. I can't remember specifics, but i'm sure someone can find the increase in HP it takes for ever 10 mph over 100.
The 2003 Cobra runs 0-150 in 30 seconds, stock.
This is with a 12.9@112 mph 1/4 mile.
A TTA IS WAY MORE AERODYNAMIC than a 2003 Cobra.
A Stock Turbo, Stock Injector, Stock Turbo TTA can run low 12's at 114 using standard recipe's.
There is NO reason that a TTA with recipe mods wouldn't run a minimum of 150 mph in 30 seconds, if not higher (155-160).
having run 0-150 more than a few times, 0-130 comes pretty fast (less than 1/2 mile). You cover the same 1/2 mile going from 130 to 150+ (in about 1/2 the time as the first 1/2 mile).

I run the 1/8 at 7.2 at 99.4. So thats 0-100 in 7.3.. I can get to 122 in 11.2.. so 0-130 would = 13 seconds?
depends depends depends.. driver, mods, tuning, etc.
Stock turbo, stock fuel pump, etc start to run out.. with a little work..these cars scream on the top.
Stock block, crank, rods, pistons.. I dyno'd 512 RWHP 648 TQ yesterday on 93 octane plus the alky injection. 24PSI boost peak.
List of mods $$$ under $5K plus labor.
Heads, intake, cam, Dp, fuel pump, adj reg, thermostat, 9x11 conv, alky kit, chip, turbo, IC, subframes, strut tower brace.

Razor, if you don't mind, what turbo are you running? What do you have to say about the TTA's? I'm stuck on which one to buy? Another Gn/ TTA???? I can't make my mind up...... My plans, car shows, mid 11 sec. Not a daily driver. What do you think??? GN or TTA

Damn those are awesome numbers. I'm sure that is a really good sized turbo, ported heads and intake. I would be shocked for the stock heads to flow enough to make that kind of power on pump gas.

I highly doubt that was less than 5K with labor. As always, there is atleast 2K plus in mods missing. I'm sure you didn't touch the exhaust, the stock trans is in there ( a grenade if it is) & the stock converter is still in there (another grenade waiting to balloon). In my many years of drag racing, I have learned that everyone, unless they have 100% of the receipts in hand, is off buy a lot when telling you what was spent to make alot of power.
Huh?
TTA89 ran 11.20's@123+ with a TE51 and Injectors with an internally stock motor/trans. Truth be known LOTS of TTA's have run similar numbers with untouched motors and light mods.
Razor's accomplishment is that he has run similar numbers with Alchy and pump gas (hence the ported heads).
MOST of the mods of my 11.53@118 T-type were done by me for zero dollars. I'm pretty sure that with my home ported heads ($350 spent) and a set of 55lb injectors ($250 with chips), my car would run 11.20's@120+ mph and it's not a more aerodynamic TTA.
We've all seen people with 4-5 times as much money/mods in their cars and they don't run as fast. That doesn't mean people who know what they are doing can't.
I forget that alot of these parts are bought new/used from other people. I'm not saying that it can't be done, It has just been my experience that people are usually wrong about what was spent.
I went 10s on my stock 99 GT longblock, trans, rear, axles, etc with a turbo system, fuel and tuning, but it didn't make it a good idea. When the time comes, the trans and engine will meet a violent death and the cost quickly climbs.
As always, we stray from the topic. His question is about a stock TTA and 30 seconds is a reasonable time to 130 mph.

Turbo is a TE67 w/69 trim. My 51 got upgraded at Limit.
Depends on how old you are, physical condition, etc . The TTA sits lower to the ground, rides like a truck, nobody knows about it, and parts are hard to get. on the flip side it has the instrumentation the GN should of had, suspension a GN would kill for, better brakes, better aerodynamics, etc. If you go the TTA route, get a low mile one and save yourself the headache of locating hard to find items. cant say the same for the GN thos since most of the parts are easier to locate.
If your overweight(fat) or aged(old).. it gets tough getting in and out of the car.
I've had both.. liked both.. but they are the same motor in two diametrically different cars.
By looks.. the GN commands way way more attention.
Marc,
Quote... List of mods $$$ under $5K plus labor.
PLUS LABOR
Tranny has been rebuilt twice.. part of riding the roller coaster. My last build cost me 850.00.
Heres a list of costs involved
Heads.. trade done.. used.. lets say 1000.00
Cam and lifters 175.00
Turbo new 675.00
Fuel pump 75.00
TQ converter 675.00
THDP 550.00
SSM subframes 150.00
Thermostat 10.00
Ported intake used 200.00
Front mount was a trade for stocker(stocker went 11.40)
Adj regulator 110
Strut tower brace used 75.00
Mini starter 100.00
ME-r chip 550.00
Scanmaster 200.00
Injectors 200.00(off a board member)
Modded ecm 125.00
Alky kit .. priceless
Some pieces one takes off and upgrades whenever possible. They still have value. So its not like your replacing broken items. Examples is I sold my stock TTA heads for 275.00. The stock intake has value, as does the TTA downpipe.
Above parts are 4375 plus the alky kit
Car did run an on BFG drag radials an 11.40 with the 51 turbo, stock IC, with an TT chip.
Yeah its stock with a water kit
thats what I tell em at the track.
