(03-05-03) The tuning in Atlanta went very well.
Matt, The Hitman, is a master with the Haltech. Matt spent two hours
working, prodding, tweaking, adjusting, smoothing and adding pure magic to
the Beast. The end result is a super smooth, powerful engine with
excellent low end and top end performance. The net result was a 19
psi pull at 340.5 rwhp. Thank you Matt for your excellent work.
Also, thanks to Brian Hill in Atlanta for making the arrangements for Matt
to be in Atlanta. http://www.mr2beast.com/images/dynoatl.jpg
(02-01-03) Currently, at 1750 miles, the engine
is running very well. The boost has been turned back up to 21 psi.
There was an initial bit of oil smoke from the engine due to the Total
Seal rings not sealing. 20 pulls on the dyno at 17 psi broke the
rings in and put a stop to the smoke. The A/F was set a little on
the rich side. That will be leaned on Feb 7, 2003 when the famous
"Hitman" from AU gets the chance to work his magic on the Haltech in
Atlanta, GA . I will be switching back to Mobile One oil prior to
the Atlanta trip.
(02-12-02) The engine is back in
the car and running well with 300 miles on the clock. It's very
smooth and seems to have near normal throttle response. It was
suggested that the removal of the TVIS and the switch to lower compression
pistons (8.3 to 1) would make a big change in bottom end
performance. Boost is being limited to 5 psi during break-in and
it's difficult to feel any real difference. The car will be driven
to Atlanta to have the A/F ratio checked in several weeks. One other
change is a switch to NPG+ coolant. The exhaust side water passages
were opened up to 6mm by drilling all the way through to the main water
chamber in the head. This should help cooling on the exhaust
side. So far, temps are normal and the engine is running well.
(01-25-02) Update: During the process of
the most recent engine rebuild it was discovered that the crankshaft has
been rubbing on the block. We believe that this was due to excess
clutch pressure causing the crank to "walk". The thrust
washers were found in the oil pan during inspection. The clutch was
removed and is being sent to RPS for evaluation. A stock clutch will
be fitted to the car until the cause can be determined. I new short
block was purchased, bored to 20 over to fit the 8.3 to one pistons and
used in the assembly of the engine. HKS 264 cams are replacing the
Webcams. Cam timing is now set to stock specs. Photos of the engine
prior to installation can be seen below.
(10-6-01) There are several stages
of engine development shown on this page. The photos that show the
refrigerated air/water intercooler core on top of the engine is the latest
design. At the present time (Oct, 01)
the intercooler project is taking a front row seat in my agenda. I
have not taken many photos of the engine during this phase because the
dominant IC core blocks much of the engine. The plan is to coat the
IC core with ceramic coating soon to help block heat from the engine. This version of the engine
which is managed by a Haltech E6k running 850cc injectors has been very
dependable. It is one of the best street engines I have had in the
car. It is smooth, powerful and has excellent drivability.
It's currently running 17 psi of boost on a blend of Amoco 93 and 100
octane non leaded fuel. The three photos below were taken during
September 2001. The data from the RAWIC temp
testing can be found in the "What's New This Week"
section (go to top of page one.) This testing is ongoing and plans
are to install a front mounted heat exchanger later this month. We
discovered that the heat exchangers in the top of the trunk lid were
acting in reverse; picking up heat exiting from the new engine lid and
adding it to the intercooler causing detonation at above 10 psi.
After NOPI we quickly removed them and water temps went back to
normal. That's one of the reasons I am a believer in the J&S
Safeguard. It retards the offending cylinder when detonation starts.
Each rebuild of my engine is between $5500 and $7500. The J&S is
about $500. That's a no brainer, right?

Engine Photos with Trunk Mounted
Intercooler
Note: Many of you may be
planning to build a trunk mounted intercooler for your cars. The
photos below may assist you with the engine compartment planning.
This intercooler has now been removed from the Beast and replaced with the
newer RAWIC. See the "Trunk IC" section for more details.
The photos shown below with the trunk mounted intercooler were taken in January 2001. They show the
turbo with stage 3 turbine,
Turbo XS BOV, 12v blower attached to TOMS scoop (used to blow hot air from
under the heat shield), Alcohol/Water injection pipe into throttle body,
and TRD fuel regulator. Jim says, "I show the engine to a lot
of MR2 owners, many of whom say, what kind of engine is that?"
It really doesn't look much like the stock 3SGTE anymore.
Seeing it in person is startling!
The car is now in Miami at Toyomoto having a Haltech engine management
system, 850 cc injectors, Blitz rail, installed (Jan. 2001). Dyno
tuning was completed on March 6th. Lance called to tell about the
progress. The car was run at 10 psi during the Haltec set up and
produced 250 rwhp. It was run again the next day at 15 psi and 290
rwhp. Lance said that he decided not to run it at 20 psi. I
will take the car to Nashville, TN and run it for max power at a later
date.
The Beast is back home! March, 17 2001 (Saturday) The
Beast arrived by covered transport from Miami. I rode down to
a local school parking lot where the transport truck unloaded the
car. It was good to hear it run again. Once back home, my son
and I took it out for the first test run on home territory. It runs
very strong, without the occasional hesitation from detonation retard it
experienced before. It is super smooth all the way to redline.
It also has more power over a wider range of RPM. The wider torque
curve makes the car extremely flexible and even more user friendly.
We have had it on the road 5 or 6 times in different conditions and it
never fails to deliver the goods. I like it!
SE2001 MR2 owners drive the Beast!
SE2001, the South Eastern MR2 meet, provided an opportunity for a
number of different people to drive the Beast and comment on the recent
addition of the Haltech and 850cc injectors. I asked specific people
who have had previous experience with high performance cars to take the
car for a short drive. I was most interested in their comments after
returning. Nearly all of the drivers had something to say about the
way the power is delivered. I had the boost turned down to 18 psi
(normal is 21 psi) which was well over 300 RWHP. One driver said
that the car was so smooth in acceleration that he was over 100 mph on a
local road before he realized it. Another said the the power was
fantastic but the way it developed surprised him. Most of the
drivers were used to some lag followed by one big "hit" in other
high performance MR2's. The Beast no longer has the "hit"
associated with a narrow power curve but pulls hard from lower RPM all the
way to the 7500 RPM ignition cut. Most of the drivers said that the
tach lagged behind the engine and that they hit the limiter before they
realized it. My thanks to all those who volunteered their time and
provided feedback on the car.

The jury is still out on the change to the RED cam cover.
Isidro Castillo made me a great deal on one that he had powder
coated for his own engine. Every time I open the engine lid it
hits me right between the eyes. Actually, the more I see it,
the better I like it.
