Phatridz SRT-4 Goes Low 9's @ 155 mph!

Mike B. · Mar 24, 2003

Anyone else see the latest Mopar Now yet? Cox and Crawford are doing some amazing things with this car! Some tidbits of information that I found interesting about the SRT-4 engine:

They are putting 825 HP through the engine using the stock block (.096 over bore and block filled with Hard Blok), stock crank, stock head (ported and water ports welded closed), stock bearings, valve seals, lash adjusters, oil system, and ignition coil.

Here are some custom/aftermarket parts they used:
AFX underdrive pulley, Cometic head gasket, custom Crane cam, Crane adjustable cam gears, Crane springs and retainers, T72 turbo, custom header, custom intake, custom fuel rail, 160 lb/hr injectors, 90mm TB, JE pistons, FM rods, etc.

They are using a good ol' 31TH auto transmission, just like every smart racer does, right? :wink: Also interesting, they gained 50 hp by switching to an MP 135 amp alternator for the Viper. No, you will not get 50 additional ponies by doing this.

Interesting stuff! It's nice to know there's a good strong engine under the hood!

Good job! That's some serious power they're putting down there. I'm not sure if I'm a big fan of using epoxy to fill the block though. I'd rather get it resleeved by AEBS or Golden Eagle or something... RSM. Those are some awesome numbers...

lifeisdeath · Mar 25, 2003

i will probably go the AEBS route depending on $$$

Remember the SRT has an iron block. I don't see much need for re-sleeving the block unless you want to completely change the bore or stroke of the motor.

What is a T72 turbo unit? I never heard of this one. What was the boost set too?

Was there any one with a 4-cylinder made it over 200MPH (1/4 mile run)?

RedSRT4Me · Mar 27, 2003

I believe the T72 is a greddy unit. Similar to there T66 or t88 etc.

to build the block i would prolly just add wiseco pistons to the stock SRT rods. You can get the pistons from bob stockum.

you can get a T78 from turbonetics.

RedSRT4Me · Mar 27, 2003

so in that case they are garret turbos. And then I;m sure turbonetics and greddy add their own spice to them and add $$$ to their products

lifeisdeath · Mar 28, 2003

turbonetics makes their own turbos, like garrett. they do not resell others turbos.

RedSRT4Me · Mar 28, 2003

hrm, why does turbonetics call them the same model numbers as garret?

OK, would this hookup to the oem turbo manifold or would you need a custom built version?

What is the difference between TD04 and the T72?

RedSRT4Me · Mar 28, 2003

TDO4 is a mistu compressor housing. T72 is a garret. The difference will be the flange on your manifold you'll need to fit the t72 which by the way is a BF turbo.

"With a wide range of flow capacities (TSO4, T61, T64, T66, T70, T72 and T76 - see compressor maps on pages 18 - 23) capable of supporting 600 to 1200 HP with a “single” turbo, the “T-SERIES” is the only true custom turbo family designed exclusively for racing applications! "
