Assume they're were 2 identical Supra's with the same mods, with cams, but the only thing different was the turbo kit. One Supra had the SP60 kit, the other had the HKS kit. From a dead stop, would the car with the HKS kit be left behind quite a bit? Or would it keep it's ground and then leave the SP car behind after boost works up? I live around New Orleans and most racing done around here is from stoplights, so races usually don't happen from a 70mph roll or something of the sort. Thanks for the help.

the hks twin car might be left off the line a bit due to lag, but it would kill the sp60 car on the top end. with people pulling 1.5-1.6 60ft times with t88's i wouldnt doubt the bigger turbo can take it from the stop and top end with the right driver

I will gladly race a HKS 2835 car in any of our SP60 or 57 cars on the street. I bet I can win up to at least 80 mph 10 out of 10 times. I know this...... cause we have done it!!


On the street the HKS twin car will either bog, or spin, or fry the clutch trying to slip it. There is not a drag radial in the world that can handle HKS twins when they come on suddenly. Basically the smaller turbo car will have less lag, and a broader torque curve as not to blow the tires....... with two good drivers, it really would not be close!!


Ive done this race a few times driving both cars, when I was in the HKS twin car, the SP60 car got me by at least 5 cars. I spun, then bogged letting off, then spun. I did not catch the other car until well over 100. Now this was with a customers car that I did not want to abuse his clutch........

I'd take an HKS 2835 kit all day long over ANY single kit, PHR or SP. How many supra's do you see a twin setup compared to a single? Not only that but twin setup will definately look prettier underneath the hood. If you have the money to do it get the HKS 2835 or 3037. If I had to do it all over again I would choose that over my PHR Stage 2+ kit. Damn I can't wait till it shows up on my door step!

-Hmmm...choosing the HKS twins, because they look prettier under the hood??????

Correct me if i'm wrong, but most of those killer 60' times on big turbo cars (t88, hks twins) were done on ET drags or ET Streets..neither is a tire you'll see many people rolling on around town!

So, unless you run into Angel, Jesus, Ara..etc...rolling next to you on slicks - I think the SP60 would run the big turbo from a stop.

-screw it, build an auto/big turbo/call it a day....

you'd take the start but when the TWINS or T78,T88 kicks will make you look like a civic dx VS supra

Been there done that

I'm waiting to see someone running no stops all out.

HKS2535 or 2540 twins
OS Giken Twin or AZ Clutch (when bugs are figured out)
Mueller lightweight flywheel
Custom Carbon Driveshaft

AND

A Racelogic TC..

I believ with proper tuning a smaller twin can (look killer for those who want that) and perform with the singles without giving up all top end. My only question is why has no one else tried this? HKS sell a starter kit for a custom twin setup including everything but the turbos. Then all it takes is locating the right turbos for you from the right retailer...

The trick in extracting the maximum driveability out of big twins is to properly balance the power output. Good sticky tires are a must, as well as a 2-step turbo launch box. If you can build 4-5 PSI off the line and have the tires hold w/out major spin, you can pull some decent 60-ft times and/or launch more competitively against a smaller turbo. After a good launch, depending on the lenght of the race, big turbos will do the rest.

Also, it is very important what size A/R are those HSK twins you are comparing to SP60. Street version is .50, Powerhouse variety is .61 and BIG TWINS are .73 A/R on the exhaust side. For example Walser the Hayabusa Killer is running .73 twins.

BTW I know a guy running 0.61 A/R HKS twins on stock fuel at approx 15 PSI. He says car has excellent power that is easily controllable and pretty well balanced.
