More pics of inside front and back please!!!!

its more the nice cushiony wrinkle sidewall that a taller tire affords aside from larger contact patch.
agx's with the rebound only setting set to stiff up front and some nice double adjustable rear with heavy springs would be a good ticket but we're pretty well stuck on the traction bars for keeping the front drivetrain in play off the line
still wiring up the new lights and running 220 for the compressor/welders for the 442's new home..shortly after the new rear powertrain is ready to go into our 90 trofeo rear cradle lol

We will be going with coil overs for adjustability with AGX shocks to try and help reduce weight transfer.
The twin engine project was put on ice... well sort of.
I decided the smartest thing to do both for fun and also for the interest of twin engine build is to build the fastest Grand Prix parts car lol...
I will be putting a thread up. Basically I will be using my parts car as a mule for testing our custom turbo kit. We basically invested as little as possible in the car. Whatever we invested can be transferred to the twin engine car.
. We used as many parts laying in the shop in order to reduce investment.
Anyhow you can read up on it in my other thread !
Once this turbocharged car runs the numbers I would I will be using the same set up in the rear engine of the twin engine car.

I'll make this easy on everybody....

save yer dough and only get the front agx's
the adjustment is only on rebound so only the front would get good use out of the stiff setting, good options are just gr2 or CompG/police/taxi rear struts
saw the turbo setup, these love t3 hotsides if they arent too small, boost so fast youll have a blast trying to make the trans live lol

It's small hot size GT30R series turbine wheel.
I will test it and if it's too quick of a spool, I will go with .82 AR.
It is a precision housing which flows more then the garrett.

we are at .82 t3 t70. damn good ar for the turbine size though if they had em id run slightly larger so we can lose some bottom end tq
deffinatly keep it for the rear motor.
we're building for mid/top end power up front and mostly low/mid in the rear, its one reason we are looking into making the rear engine the primary, as the front would be out of its league hauling the weight around driving with a single engine.
i know your going for straight drag car, but dude these ****ers are so much fun with on demand over/understeer that trust me when i say your going to want to hash it out on a roadcourse with two independent throttles.
**** ya might as well go to a whorehouse with a chastity belt on

Since you guys modify everything anyhow.. Can't we slap a set of drag bags or load leveling bags onto the back of one of these things? Did it on the Bonneville and damn.. the weight transfer went to nearly nothing. That helped me break the **** out of a lot more parts.

I have a pair of semi truck cab air springs that I was planning to use on the turbo regal
06-06-2014
wow i forgot about this thread lol. I wanna see this in person

Thank you Captain Crazyman

I want to build a track car unfortunately the budget is not there. Drag racing and road racing is 4th in my priority list and I have too many hobbies.
The twin engine GTP has weight in the wrong areas to be nimble... the weight is better center and that would be the opposite. The total weight would need massive brakes to be able to run hard on a road course. Too heavy...
The car I want to build which I planned for a few years, well someone did the exact car I had in my head. I mean it's the same drivetrain idea, same engine, same layout, same size, almost everything.
And the car is stupid fast around a course....
check it out:
mid engine (passenger side) two Hayabusa engines, sequential trans AWD !!!!
400HP 1200 lbs !
The version I wanted to do was a turbo ZX14 engine in the same spot.
Chain drivent LSD diffs front and back.

Ok Twin engine project has progress as our Guinea pig parts car is succesfully turboed with a minimal budget and mostly stock parts.
Here's our parts car with a single engine in front.
That set up is going in the rear engine and front engine of the twin engine car.
It's only running 16 psi, will bring it up to 20 psi and it will run deep 11s with a single engine, can't wait to see what 2 will do.
06-11-2014
ok. i want a turbo now, f this damn m90 blower lol
are you in second gear full time? like no 3 rd either? the tach is always way up there. if not at red line, one stout parts car!
06-11-2014
The speedo is off it's been calibrated for 23" tires (slicks) but I'm running 26" tires in the video above (so it reads low)
I believe it shifted in the longer runs into 3rd gear.
I make it shift early via shifter from 2nd to 3rd gear.
It never goes into 1st gear there is an issue with the solenoid inside the trans got a code
(it happened right after we got done working on the car, it ran perfect before, not sure what happened)
But I think I might leave it like that, I got PLENTY power to spin my slicks in 2nd gear and I don't lose time in the shift. Also could be easier on the input shaft as there is shock load between the 1st and 2nd gear shift.
It has so much torque it feels like a CVT transmission from a turbo sled. Endless pull at any RPM , instant boost too much fun.

BTW the M90 is junk compared to a turbo. It's not even fair.
Lots of HP loss through the supercharger and heat created. I have a massive intercooler on this one and the air intake pipe is COLD, not warm, cold, after running the car hard.
06-11-2014
the giggling from the two of you spoke for its self lol
06-11-2014
Not me just him i already giggled all day he was the last to ride i had already 25 plus test run done lol

im fully aware its apples and oranges. clearly oranges are taster lol
06-11-2014
Anyone who knows turbos and superchargers know it's apples to oranges BUT...
We just did back to back changes with very little upgrade. Many upgrade cams, headers change tunes, change MAF, change injectors.
We kept almost everything the same. We see the true difference.
It's night and day. I mean, I feel like at the same boost we make 150HP more.
I expected an easy 75HP gain from the turbo at the same boost but expected 20psi + to really start getting solid performance.
Nope. Stock cams, stock heads, stock block, stock manifolds. (modified mid pipe)
