biglady112's LSR 1989 Dodge Colt

Steve; What Dan was telling you is that no mater what you do to your car it can't run in Modified Sport. You need a sports car to run in Modified sport.

The boys in the yellow Galant didn't just run off the end of the road and go 218.

(But I hear they were geared for 307!)

4.153 axle, .666 gear, current "small" street tire (won't ever see the salt)- 205/60/14. = 216-217@8500. This engine has seen over 8000 probably over 100 times in the last six months. So she holds together and cruises along just fine up there. The new turbo will have no choice but to live up there. It won't even spool until then.

Looks like fuzzy math.     I hope you are able to go really fast but there's a ton of other factors beside gear ratios, tire size and rpm at play here.  My car will pull 9000rpm and with my tire size and overall ratios in 5th gear that works out to about 199 mph.  The problem is that it ain't gonna happen.  The only way my car will ever come close to 9000rpm in high gear would be on a dyno.  In the real world there is all that air that we have to push outa the way.  That takes horsepower, torque and traction.  After you budget gets depleted chasing those three then you have hit the wall.  That leaves you with the need to reduce frontal area, drag and all that other aerodynamic weird science stuff.  Good luck and keep having fun . . that's more important than anything else (except safety)

Good luck with the project Steve!

I have a 2006, 2007, and 2008 rule book here at the house if you want to look through them.
As you know I also have a library of pictures if you want to do some photo research on any of your ideas.

Based on your trap speeds and weight at Bandimere you are making about 320 hp to the wheels right now, about the same as I am on the WRX with the same small turbo. There are as you know several street driven cars with the mitsu engine in them around Denver that are making in the 400-500 hp range so necessary hp should not be a problem for you when you get to that point.

Our air conditions here at about 55 deg F. are about the same as down at Bonneville during the summer so you can dyno in real world air conditions without much trouble. In fact you will gain power going down to Bonneville from what you see here.

I know it is a long project and you have lots to do, so keep plugging away as you sort things out.

Here is the latest round of modifications to the car. Starting to make the power I am looking for. Car is currently at 23psi with the new turbo. I also need to get pictures of the new surge tank I built for the coolant. I am now on a 12.5 gallon radiator system.

Wow a lot has happened since I last posted here. I forgot I started a little thread here. I have been keeping a log elsewhere, so I forgot. I will make sure to keep with the updates from here on out.


Small update. I gto all the last little details done tonight. I am just short the cylinder head now. I have all the parts to put the new head on. New used head bolts, head gasket, one more 10x1.25 stud, and the 2.0L intake completely assembled and ready to bolt on. That includes the coil pack, throttle body, map sensor, and vacuum lines. As soon as I get the head back it should fly together.

Only other detail I did tonight was get the front bumper ready for more airflow to the radiator. My radiator has 11 rows. Well, only two were seeing any airflow. So a little trimming was in order. I just have to take it apart and plasma cut the actual bumper some more. That is all for now.

Here are some pictures when the new head went on. It is a picture of the new Mitsubishi MLS headgasket and a picture of proof my my kick ass little 4G61.

Well, got the fuel pump rewired today. It gave me a good 25% at least more fuel to work with. So that is exciting. The car is making progress. It really responded to more fuel as well. With it running pig rich at 21psi, it said I was at only 70% duty cycles now. I think I can get it under 60% with the current boost level. I need to add we wired this different than any other rewire write up I have ever seen. Jason and I wired the pump/relay directly to the alternator. I am just guessing here, but I bet I gained anywhere from 2-3 volts MORE under throttle to the pump. It made a bigger difference than I could have ever imagined.

Before I can turn it up though, I need to put a new timing belt tensioner on the car. It is going out and I do not trust it to rev to 8500 all day at this point. So before the car comes out again, that needs to happen. Hopefully I can get a full time job soon, as my new part time is not enough, then I can get it done and get the vent system for the cooling system. Then we will be in business. This and a set of axles and I am ready for test in the quarter mile.

The cooling system does indeed pressurize. We removed the fill for the tank and it was a rather large burst of air that came out. And that was after just idling the car. I am sure 8500rpm of spinning the water pump really boils things up in there.

Two of the newest changes. More to follow in the next 1-2 weeks.

[biglady112]

First step towards converting to a full 10 injector/methonal setup.

[biglady112]

First step towards streamlining the car. Both mirrors are now gone.

Been busy. With the countless trips to the welder getting the design down for the new fuel system and basically keeping a fire under his ass, here is the first part of the next evolution in the car.

The pictures speak for themselves. But I will give a little run down.

Built a switch panel that will also hold the parachute release handle
Got the new -4 vacuum line setup more or less ready to drop in
Added a 5" stack to the inlet of the turbo. While we were in there we added a -10 male bung to recirculate the crankcase pressure(IE- vacuum pump)
Not pictured is the valve cover with its single -10 vent
Ditched the catch can
Relocated the battery finally after over three years
Upgraded the 40A cut off switch to a 175A
Picture showing the empty engine bay with no battery now

Pictures hopefully coming soon of the complete vacuum setup. The fuel system is still 6-8 weeks out from being done, so nothing to show yet.

Here you go.

Things are looking really good now. Been making really good money lately and had no choice but to spend it on the colt.

I will have the awesome pictures on monday when my shipment comes in from magnafuel. But these are the parts I have in hand today. I am moving along nicely for a change. Most likely will be buying the parachute before the end of the month.

5 gallon JAZ fuel cell


Fuel cell brackets, 100psi mechanical fuel gauge, -10 bulkhead fitting for cell, -8 cap for extra feed for cell, 1/8npt to -4 fitting for boost reference for new regulator.
