VTEC Prelude Vs. Type SH

[projectgsr]

I was just wondering the major difference between a 98' VTEC Prelude engine and a 98' Type SH engine. I know the SH has like 200 hp stock, but is it the same block, pistons, cams, ect. I'm more familiar with the B series engine's. Any help would be very appreciated.

The motors are identical. The trannies are different.

Yeah, the engines are identical but the transmissions are different.

which model tranny has more acceleration?

[projectgsr]

Oh OK, now I get it. That's interesting. For some reason I always thought that the regular VTEC car only had like 180 or 190 hp. So why do they call it Type SH anyways. Can anybody answer that? And is the SH tranny gear ratio much better for racing?

the difference in acceleration between the two comes from a very slight weight disadvantage for the SH, a mere 88lbs. the tranny won't affect the difference in acceleration. he gear ratios are the same. their essentiall the same gearbox, but the SH has the ATTS unit attached to its tranny.

and search for differences on the SH and base model, you'll find that this topic has been discussed many times over.

They call it the Type-SH for "Super Handling". The Type-SH model has something called ATTS (Active Torque Transfer System). To put it simply, it basically sends more power to the outside wheel when cornering making it spin 15% faster than the inside wheel. Somewhat of a bastardized version of an LSD. Gear Ratios remain the same. Also note that the front suspension on the Type-SH is different (differs in that the upper and lower control arm designs were changed to reduce torque steer, also slightly stiffer) but can be considered negligible.

The only time a Type-SH would show any advantages over a Base is through things like Autocross or Circuit racing. But when it comes to straight line drag racing, the Base model edges out the Type-SH ever so slightly.

So your saying that the SH weighs a little bit more because of the suspension. Well that kinda sucks because that's what I'm buying in a couple of day's. But you know what, actually I prefer it to have better handling. I'm not too big on drag racing. If I was really that worried about weight I would have kept my GSR or would have bought a CRX. But are you saying that it really doesn't handle that much better when you say that it's a "bastardized version of Limited Slip Differential"?

No, the SH handles way better, he just means its kinda a different version of a limited slip. As said before ATTS sends power to the outside wheel which reduces understeer, and can throw some oversteer at you. The SH weighs a bit more because of the ATTS system, not the suspension. The SH will barely be slower so it really doesnt matter, if your a great driver you'd outrun a base lude with an OK driver.
