help with set up for low 11's high 10's

[ruboosted2]

I am building my 87 tr to hopefully run low11's at least. What other parts will i need to achieve this goal? I have- Te61 turbo( freshly rebuilt) 42.5lb injectors, kenne belle intercooler( a big one) tranny has been rebuilt and 3000 stahl installed, air bags and drag shocks on the rear, adj fuel reg, wal 340, 10mm wires, sealed power forged pistons. stock heads ported, stock crank- rods-block--- what other parts?- lower end? Iam not sure what kind of headers I have- no pictures i have seen look like them- anywhere else have a guide so i know what i got?!

any imput would be very helpful and apreciated- thanx alot everyone!!

-giddieup-

P.S. I have a 11.48 sec 383 nos monte carlo to beat, and a 10.98 WS6 Nos to run with next season!!!! THANX!!!!!!!!!

depends a lot on what your car weighs, but prolly bigger injectors (at least 50's), high boost, 116 gas, slicks, high boost launch (trans brake preferred), roll bar, and for 10's trans blanket and sfi balancer

 

[c&cgn]

Way more injector for sure. I ran out of fuel with 50's around 11.20's. I would go right to the High Z 57's.

And to add to what Woody mentioned, you'll also need upgraded axles with c-clip eliminators if you are going to run 10's. You'll need the axles upgraded for sure either way. Once a car passes 11.50's you are playing with fire if you don't upgrade you axles.

I thought MSD 50's were good well into the 10's

 

[azgn]

if you are brave

(and like to run 100% duty cycle)

not recommended for the faint of heart and those without a wideband 02 and FAST

Depends on your combo, I guess. I know a couple of guys who are running high 10's that are both using the 50's. They are not running EGT's as far as i know, so maybe in their case, not knowing is better ? I can tell you with EGT's of 1700* I was not going to risk my motor by pushing it further. I have since upgraded to Delphi 75's. No more fuel problems for me

BTW, Woody, I was well over 100% DC. More like 115%

 

[DonnieShort]

Well I'm glad to find this out now instead of later

What seems to be the limit on the 50's? I'm getting parts together for a motor to do over the winter and ( high ) 10's is the target and I want to make sure I have plenty of injector to get me there safe.

why do you think i am upgrading my injectors? 50's are excellent injectors for stock or near stock motored cars with slightly bigger turbos...if you want to get serious the 57's are minimum...those injectors don't require an ecm mod either which is cool

43# injectors will support low 11's. Heck I went 10.83 on 43's. I run a static FP of 50psi......and my car weights only 3200#.
I'd say 50's should easily go 11.00 or 10.90's, depending on how heavy the car.

One thing I learned was that the stock voltage feed B+ to the injectors is inadequate (pink wire-18 or 20 gage I think). At least with the batch DFI I am using. Run 12 gage wire to feed B+ to the injectors and they instantly deliver more fuel! Harry at PTE gave me this tip.

yeah 50's can support high 10's easily on a 3200 lb car...but when your car is a flying brick and weighs 3700+ like mine you need beefy injectors

I was unaware that you were upgrading injectors, I'm not Miss Cleo you know j/k

Don looks like we're doing the same thing over the winter. To bad Vapo isn't reasonable close to Central Ky, we could help each other out.

 

[Chris McDade]

I've gone 10.63@127 with 50lb injectors. I would say 10.50 would be the limit on 50's depending how heavy your car is.
My car is 3580 with me in it. This was done with a TA66 turbo.

Good Luck

 

[c&cgn]

I would rather err on the side of caution. I wouldn't want to tell someone that 50's are good to 10.6's and them blow up their motor running 11.0's. Every car is different, plain and simple. Maybe with more fuel pump than a Walbro 340? Maybe a double pumper would be enough to feed the 50's so that you can run 10's, but I am not willing to to find out the hard way. If the bigger injectors are available, I would go with those to be safe. Just my .02

Maybe in a 3200 pounder. But I don't know of many GN's or T's that are daily driver's or not stripped down that would meet that criteria.

Both of mine tip the scales at over 3600# dry/empty.
I too would NOT feel comfortable running 50's into the 10's

My stock motored 86 only has a little more turbo, FM intercooler, and MSD50's and running it VERY lean(O2's 750/EGT's 1680), down into the 11.60 takes them into the 89% dc area.

Just in case anyone missed your mention of the 89% DC.

Static, and erratic, can go faster for a while.......

Heres my opinion:
You dont need squat to catch the monte, just good fuel, good tires, right amount of boost, good tuning and a little practice at the track to see what she likes.
Now that WS6 is going to have you looking closely at every thing. You got to remember that the faster you go down the track the less time you have to make an improvement. An extra 20hp on a 14 second car is going to knock off more time than an extra 20hp on a 11 second car. One of the best things you can do to help your ET is to get the car to launch hard. You dont have to launch at high boost or use a T-brake to do it either. Infact a T-brake is more likely to shock the tires and make them spin. I have gone 1.462 leaving at 8psi off of the foot brake.
If you have your motor out of the car and you know for sure that you eventually want to go in the 10's w/o taking the motor back out then I would think HARD about having some caps or a girdle put on the motor.
Also you need to describe them headers or take a pick of them. If those things are hooker headers get rid of them. They will slow you down. They aren't worth the scrap iron weight you could get out of them.
I live just on the other side of bloomington off of I-74. If you want you can email me and I'll give you my contact info. We will be going to the races a few times next year. Hopefully your buddy with the WS6 can go and I'll see if I can give him a run for his money with my 100+k mile stock long block. If not I'm sure my buddy Rodger aka Nashty could humble him for you.(10.27@131)

here's what i am planning to do...57 lb/hr siemens "high impedence" injectors, PT67 turbo, PTS 9/11 3500 stall converter, PTE front mount intercooler, fresh stock block .30 over, girdle, TRW pistons, 206/206 cam, 10/10 crank, all new bearings, rods, ported and polished stock iron heads, double pumper, etc.

many guys have had good success with the 57's with large turbos...you could go 72's i guess if you wanted to run deep into the 10's but that's not really my goal...i just don't want to spend the extra money on those size injectors plus getting the ecm modded...

 

[ruboosted2]

thanks eberyone

thanks to everyone for advice- so we've decided on 57# ers and better axles- scanmaster- alky- did i miss any thing??

thanks again- giddieup

I going to do bascically the same thing, but since the 50's wont get me there I'll probably go with the 72's in case I feel the need to get the et down further The motor I have now is still great but I don't want to run the risk of doing any damage trying to run it any harder. All I need to do is get the motor stuff together since I already have a set of full ported and polished race irons ready to go on it. I've got the FMIC and converter, although it may need a restall for the turbo which I was thinking of the GT 40. But the PT67 would be a good choice too. One of the differences we have is I'm going to go with the Comp Cams 212/212 roller and roller valvetrain. It may be overkill, but since I'm into it I might as well do it the first time.

Spending the money on a good fuel system is about the best advice anyone can give. It may cost a little more to have MURPHY built in but will also save you some head gaskets or motor rebuilds. The extra $150.00 to mod the ECM is well worth it and then the sky is the limit! I don't know how much the 57's cost but the last set of 50's I bought was damn close to a set of new 83's including the ECM mod. I love my 83's! Idles superb and has great street manners! I am down to the lowest settings on my thumbwheel and FP and still can only manage a high 1400 EGT going 11.4. Plenty-o-room!
