THANKS TO MR CHRIS BELL WE HAVE A PRECISION LARGE FRAME 98/85MM TURBO. WE ARE BUILDING A 275X CAR AND MY QUESTION IS HOW FAST HAS PEOPLE GONE WITH THIS TURBO? I CANT FIND ALOT ON THIS TURBO AND I KNOW THIS IS THE RIGHT PLACE TO FIND OUT.

The quickest and fastest I've seen was Sean Lyon at NMRA World Finals in Bowling Green. He ran 7.47 at 190 mph but i think he was 3275 weight. If I remember right his 1/8 mile was 4.76 at 151. It was definitely in the 4.70s just don't remember exactly where but the .76 sounds right.

Which is it? A 98, or a 85? Gotta pick one.

What does "necked down" mean? 98 with an 85 mm reducer?

A LF85 will make as much or more power than the old school turbo pictured above.

most of the time when you see 98/88 or 98/85 all this means is they took a 98 mm wheel and cut it down to a actully 88 or 85 what ever the case will be. they did this years back because there wasnt a off the shelf large frame 88 or large 85. the new x275 turbos will make more power than these older units

if its just a reduced 98 mm its not legal for x275 anyway
