How fast could this get me?

[MauDeuce50]

On a motor with 124xxx miles, could a RJC power plate, fuel pump with hot wire kit, 60 lb injectors, turbo tweak chip, and cold air kit get me into the very very high 12s? If not, what would?The car already has a high flowing exhaust system by the way. Thanks for any input!

 

[turbo89]

it would go faster as long as motor is sound.. put valve springs in it and it should click off mid 12's all day

you are missing the most important ingredient and thats boost
you wont get there at stock boost or even what 93 will allow
you will need to raise boost and to do that you will need octane and chip tweaked for it or alky injection
even with that you will still need traction

 

[Blaze]

Yes, it can get you high 12's. Add race fuel & turn up the boost. Slicks or drag radials would help alot also. Boost gauge & scanmaster for monitoring & tuning.

would it get there without cranking up the boost though? I dont have much tuning experience so I dont want to mess anything up, especially since I drive it almost every day

Ok thanks a scanmaster will be the first think on my list

13- 14 psi wont cut it... either run race gas or alky or E85 and turn the wick up to 22+ psi.... run a scan tool for tuning / check for knock... it will easily run what you want

These cars are a joke on 93 octane fuel.. and if you don't run good fuel in them you are missing the point of owning a turbo buick ... they are night and day with good fuel + Higher Boost

you need 332hp at 3700lb to get 13.0
nothing youve done really changed it from the 245hp it came from factory and thats assuming that what you have still works 100% as it should ,

at 22 psi tuned , with alky injection , good traction and air , these cars could break into the 11s or just plain break

if you need this car for everyday to make a living
heres the old man in me talking ....


before you know it youll have the boost up and then the headgasket will pop , fix that try again and then the trains will start slipping
if this is a second or third car (a toy) and you have the finacials to play.. go for it
if you cant do the repairs yourself or cant do without the car as its your only means of transportation then ...
....get the scanmaster and use it to make sure its running correctly but leave the HP level alone .

Then don't mod it and race it.

Come on.. you make it sound like @ 22 psi and race fuel for the occasional track outing that they have a glass jaw !

@ mid to upper 12's they will take a beating until YOU say uncle ...

if he does a bit of reading on here and learns the car... with what he has ( no kr.. good fuel) it will run his numbers easily and NOT BREAK .. the problem is he will achieve his goal EASILY
and then try to push further... then the bug starts .... hi 12's is a joke for these cars on good fuel

 

[pacecarta]

if i could take you back to 87-90 they were blowing these cars up left and right and back then a 12 second run you were a guru

he may reach his goal or he may be walking

well Gee ... alot has changed since 87-90 hasn't it ...

you can break a stock one if you are determined to do so..

chip technology has gone a long way... we now have alky and E85... better tuning tools.. better tires.. better parts in general.

I don't see hi 12's breaking anything unless he detonates the hell out of it with junk fuel.

I've beat the snot out one of my TTA's for a VERY long time @ way faster than high 12's .... eventually the trans did start to slip , but a simple refresh and it was back to the races....

im not saying they will take 20+ years of thrashing @ 30 psi and live ... but give them some credit .. if you have good fuel and are in the ballpark with the tune .. they will bring you years of smiles

If I was use you I would leave well enough alone and do not stir up a hornet nest from what you just said . That's MO .

 

[pacecarta]

i give the stock a lot of credit ,
ran 12.0s for years on stock unopened motor and turbo and even went low 11s before the cam lobe gave up and had over 130k
at low 12.xs the trans went , and you call that a simple refresh like its a couple dollars , maybe a couple $1000 these days. and you better have another means of transportation or you may find your self unemployed
.I ran my 86 with stock block (crank rods pistons etc) for many years at low 10s (bracket raced weekly not the i made one run ), but that wasnt on a 26yrold timing set or stock head gaskets or stock trans .

the point wasnt that the 3.8 is weak but it is and only through good tune can we do what we do , in stock they can tolerate a lot of mistakes , turn it upand that all changes fast
, if you cant afford to play you shouldnt

Can't wait to see where this goes.

WOAH ! ... he is asking hi 12's ... even at a weekend warrior hi 11's it will tolerate ALOT !

What is wrong with stock head gaskets ! The Factory SEAL is hard to beat and can take a boat load of abuse...

NO point in having a turbo buick and running around on 13 psi and 91 octane .. might as well drive a volvo

200 + passes on a stock setup in the 11's how much more can you ask for.. seriously give them some credit.

and Miles don't mean shit ... seen a Bunch of GN's with < 50K miles that looked like they went through hell internally.

I can see if you were steering the guy to stay out of the mid to lower 11 second range for a daily driver.. but high 12's @ the track isn't even getting it warm.

Let the guy have some fun with the car ... that's what they were made for

 

[whitehot1]

If you are going to race it and it's your only transportation i would highly suggest you buy a second car.

The turbo regal is a blast to own and drive but when you start mods for more power and speed you are going to find the stock parts are going to fail,they were designed for 245 hp from the factory.

 

[we4Mateo]

Heck, even stock, they're just old and things break. If you can drive it every day now, it should easily do high 12's w/ race gas without breaking on a good hook.

 

[MauDeuce50]

Ok thanks for the input everybody!

 

[Mr.Spool]

pacecarta answered your question perfectly.understand the moment you turn up the boost and add proper octane and a good set of tires the trans will not last to long.im at a point where I tell people to pull it right away before you get stuck as the last stocker flaired so bad at the track it barely made it home.dont want to break it leave it stock.thats the allure of these cars in a short amount of time you can turn the stock setup into a lot of fun but it wears them out much faster.
