 |
|
The time has come for my motor rebuild in my lowlight and in going to do a 1776cc. I have some questions
1. Where do I get a DTM fan shroud?
2. Should i full flow the case?
3. Will dual 36 dells be enough carb?
4. Will the A1 sidewinder work with the DTM shroud?
I am going to drive the car everyday and i never want to rebuild the motor again is there anything I should do to keep it from spinning a berring again?

Q. 1. Where do I get a DTM fan shroud?
A. www.aircooledtechnology.com
Q. 2. Should i full flow the case?
A. Yes. Use a quality filter to catch all the crap that otherwise would wear your bearings out.
Q. 3. Will dual 36 dells be enough carb?
A. Depends on your heads and cam. Mild heads and mild cam will work perfect. 36 dells (30 vent) are the same as 40 webers
Q. 4. Will the A1 sidewinder work with the D
DTM shroud?
A. I cant afford either so I cant answer the question. Remember to match your primary size to your head/valve.
If using stock heads go with something like an Engle 100 and 8:1 compression for reliable power. If you really want the engine to last forever you MUST have a shop balance ALL rotating parts (Clutch, flywheel, crank, rods, pistons, pulley) for long bearing/engine life. You will usually have to do a valve job and new valve springs around 50K miles but the bottom end will go 100K if you do the maintenance. I would also get a deep sump if your ride is not too low and gauges are a must (CHT, Oil Temp, Oio Pressure, tach is nice too). That way if there is a problem with heat or oil pressure you can see it before it does any real damage. 
Remember more revs = shorter engine life, the more you "race" it the more maintenance is required and the faster it wears out. |

i hate running my motor above 3 grand.
I want to run a engle 120 cam and 8:1 compression and do alittle amount of head work.
My car is slammed 2 inner clicks in the rear.
I will get a tach, oil pressure, oil temp, and maybe a head temp.
I will get everything balanced.
I am going to dyno it 1 time just to see what power im gonna get im shooting for at leaset 90 to 100 HP.
Thanks for the help

also the motor that is currently in my ghia right now has 90 compression on each piston. And it has no oil pressure could i just put pistons on and fix this? I need this motor for my vert.

"shooting for at leaset 90 to 100 HP."
Not gonna happen with a mild 1776. Not even close. Maybe 70hp.
Your also hurting the motor by not reving above 3K. This is not a water cooled motor. It needs that fan speed to cool. Also no need to balance it if your not going to rev it more than 3K.
36's will run great on that motor. |

I was just looking at the DTM site and I cant figure out how to order a DTM shroud.

90 is acceptable but putting new pistons will do nothing to help oil pressure 
Maybe broken oil pump gear or incorrect pump altogether or just worn out bearings. If you ran the engine with no pressure plan on replacing the bearings at least, that is if it didnt overheat which is unlikely. Consider it junk and practice on it.
For a 1776 a DTM costing $500+ is not really necessary. Ask Jake and he will probably recommend a stock dog house set up with ALL of the factory tin and not using the Type III "cool tin" |

a 120 needs 9:1 compression to work right and sets the power in the upper rpm range. Even with a little head work stick with the 110 and 8 or 8.5:1 compression. I run my stroker 1.7 at 3200-3500 on the freeway with no problems using a stock cooling system. Above 4000 it heats up and wastes gas!!!
You definately need the CHT gauge cause that will really tell you how hot your engine is. If you were to only get two gauges get the oil temp and CHT, your idiot light (if working) will suffice for pressure.
P.S. dont get larger than a 26mm oil pump or your engine will run hot. |

Then you may not be qualified to own one.

Do NOT run the 120 with 8:1 CR and " a little head work". You need bigger valves, port and polish and ~8.5-9:1 to take advantage of that cam.
What size valves will you be using?
Remember, it's all in the combo. If you don't match up the parts you end up with an underpowered pig with a peaky or mushy powerband that will get crappy mileage and run hot.
You'll be surprised at what a 1776 with stock heads, a 110 cam and ~8:1 CR will do....especially if you have an engine that's in poor shape right now. And it sounds like you do. A 70-75HP engine will feel a LOT different than that worn out 37.8HP you're making now!

Yep. Great, reliable, proven combo that will run cool and last almost as long as a stocker. Feel free to clean up the heads a little...a mild "fluff and buff" port job.
This engine combo works well with heater boxes, too.
Be sure to run a sump and full flow.

don't know if you have a shop in mind to do you balancing and machine work, but i sent all my stuff to competition engineering. bunch of great vw guys, and fast turn around time. ask for Dan.
