If this is tied in too closely to the guess my times/power thread mods can delete.

Here is the rundown. I have a little EG hatch. B18B swap, T3/T4 60 trim. It's not my only car so that isn't an issue. Right now I'm making around 250whp, car trapped 111mph on the stock 13inch DX rims and tires. It acts like a car that traps 113-114mph from a roll (pulls bolt-on LS1's that trap in that range).

Anyway my friend has an LS1 TA with bolt-ons. We were chatting today and talking about our plans and decided that we both need to up the power just for the heck of it. I think we came to the agreement that neither of us can sell our current cars (my hatch, his TA) to it at least traps in the 125mph range lol. I don't really need something that fast, but I'm single with no kids so I gotta blow my money on something besides the ITR

So guys what will it take given the B18B's general power curve of having well matched hp and torque?

Motor will be built as needed. I just need a general idea of power levels. I'm thinking 375whp or so but not really sure. Thanks in advance.

 

your guess is probably pretty close, some variables are involved but close, i trapped 116 in a 92 cx, close to 300ish whp. so 350-375 and its there,
point of reference, another crx in town dynoed 290-295whp and is at 117-118 traps.

 

117MPH is still a long way away from 125. ur biggest problem will b traction.

i forgot to mention, on street tires, good luck.

 

2200lbs w/ driver assuming you have a good torque curve, you should do it w/ about 375whp maybe even less.

 

I would think that 400 would be your magic number.

I managed to trap 124.68 with 330 ish, but this was in a 1900 lb hatch, on slicks, with a 1.5 60 foot...

you will need a lot more power to make up the back half of the track. since your 60 foot probably wont be very impressive on street tires...


thats my opinion. good luck.

 

I was thinking street tires as it usually increases the trap, but then again trying to get down that much power might actually hender trap I guess.

Let's say I'll be running a good drag radial, but not a full slick. Basically I want the car to act like a 125mph trapping car once I have traction.

What Chris said. I trapped 120mph in a 2600lb car with 370whp.

 

true, usually the higher the 60, the higher the trap. I just wanted to give some other angles for looking at it...
